Revisiting the journey of Marine Corps veteran and climber Tony Moro. His fight against MS and the quest for the summits thrives, powered by flywheel training technology. Explore his latest triumphs, his strength training routine, and the ongoing climb to conquer the seven summits with us:

Q: Tony, it has been some time since we last read about your exploits and climbs, what has been new since the last time we heard from you?

A: Since my last article, there have been significant developments both in my mountaineering pursuits and personal life. I embarked on two challenging climbs – Denali in Alaska and Mont Blanc in Chamonix, France. Unfortunately, both attempts were thwarted, one by harsh weather and unexpected MS symptoms, and the other by a change in the guide’s plans. However, these experiences were far from futile.

On Denali, I reached Camp 2, an achievement in itself, which honed my mountaineering skills and provided invaluable insights for future climbs. Although I couldn’t summit Mont Blanc, the rock climbing experience in Chamonix was unexpectedly rewarding, pushing me beyond my previous limits and introducing me to more glacier travel and cold, wet rock climbing.

On a more personal note, I became a father to a beautiful baby girl on November 25th. Balancing fatherhood with training has been a challenge, but it’s one I’ve embraced wholeheartedly. My training regime has been rigorous and consistent, involving daily use of the kBox4, weighted ruck marches, and achieving a minimum of 10 km per day with my ruck since November 1st.

My wife has been an incredible pillar of support, encouraging me to continue my training even during critical moments like her going into labor. On her due date when her water broke, she looked at me and said “Hurry up and get your 6 miles done before taking me to the hospital.” For that, I am forever grateful, and impressed!

Professionally, I continue to push the boundaries as a high-performance coach and a human performance advisor, leveraging my experiences and ongoing PhD studies in health and human performance. My training approach using the kBox flywheel is multifaceted, focusing on pre-ruck activation drills, eccentric strength training, and conjugate-style mini-workouts for overall physical preparedness.

As I plan for my next expedition next month to Aconcagua in Argentina, the highest mountain outside the Himalayas, I am still actively seeking more sponsors and funding.

“My journey is not just about personal achievement but also about breaking barriers and inspiring others, especially those facing challenges like MS.”


I am eager to share more about my adventures, learnings, and the unique insights I’ve gained from both my successes and setbacks.

Q: How has your training been going and how has it changed, if it has changed at all leading up to new climbs?
A: My training regimen has evolved significantly, especially in light of recent events and my growing responsibilities as a new father. The core of my training still revolves around the kBox4, which has been instrumental in maintaining and enhancing my strength and endurance. Specifically, I’ve been focusing on three key aspects: pre-ruck activation drills and warm-ups, eccentric strength training, and conjugate-style mini-workouts. These elements are crucial for building the resilience and physical capacity needed for high-altitude mountaineering.

Since the birth of my daughter, time management has become even more crucial. Despite the new challenges, I’ve managed to maintain a high level of physical training. I’ve committed to daily weighted ruck marches, carrying over 50 lbs, and have successfully achieved at least 10 km per day with my ruck since November 1st. This specific regimen not only builds endurance but also closely simulates the physical demands of mountaineering with heavy gear.

In addition to this, adapting to the unexpected has become a part of my training philosophy. The climbs at Denali and Mont Blanc, though not successful in terms of summiting, have provided me with invaluable lessons in adaptability and mental resilience. The experience of climbing cold, wet rocks and undertaking glacier travel has added a new dimension to my skill set, one that I hadn’t extensively trained for but adapted to in the field. This adaptability is now an integral part of my training approach.

Furthermore, my training has become more nuanced, integrating more specific drills that cater to the unpredictable nature of mountaineering and the unique challenges posed by my MS.

“I’ve learned to listen to my body more and adjust my training intensity accordingly, ensuring that I stay at peak performance without exacerbating my condition.”


I’ve even been using the kBox for the spring ankle series made popular by coach Cal Dietz. The addition of high-volume rucking adds a fair amount of stress to the joint and once I began to feel achy in the lower limbs, I added the spring ankle drills to increase load management and resiliency. I can confirm it’s been helping immensely.

In summary, my training continues to be rigorous and focused, yet flexible and adaptive, reflecting the realities of my personal life, my health condition, and the unpredictable nature of high-altitude mountaineering. Each step of this journey adds to my experience, making me not just a stronger climber, but a more resilient individual overall.

Q: Is your training still heavily focused on eccentric overload? If so, can you share how you balance climbing and strength training as part of your routine?

A: Yes, eccentric overload continues to be a cornerstone of my training regimen, primarily due to its effectiveness in enhancing strength, improving muscle control, and reducing injury risk – all crucial for the demands of high-altitude mountaineering. However, balancing this with the specific skills and endurance needed for climbing has been key to my overall training strategy.

The kBox4 remains an essential tool in my training, particularly for eccentric overload workouts. These sessions are designed to improve my muscle’s ability to absorb and generate force, which is incredibly beneficial when carrying heavy loads uphill or controlling descents, common scenarios in mountaineering. It’s also been clutch on the days I’m on solo dad duty and can’t afford time to drive to the gym. Having the kBox at home has been one of my biggest assets in staying fit.

To balance this with climbing training, I’ve adopted a holistic approach that integrates both strength and skill-specific work. A typical week involves a combination of kBox sessions focused on eccentric overload and climbing-specific exercises. This might include light pre-ruck activation drills with the small-sized disc to prepare my joints for the load-bearing demands of mountaineering and conjugate-style mini-workouts for general physical preparedness (GPP) with the medium to large-sized discs. The GPP workouts are crucial as they contribute to overall fitness and endurance, complementing both my climbing and strength training.

Climbing training, on the other hand, is more focused on technique, agility, and endurance. This includes practicing on varied terrains and conditions to mimic the challenges of mountaineering. I ensure that my climbing sessions are strategically placed in my weekly schedule to allow adequate recovery from the high-intensity eccentric workouts. This not only prevents overtraining but also ensures that each training session is effective and safe.

Moreover, given my condition with multiple sclerosis (MS), I’m particularly mindful of how my body responds to training stress. I regularly adjust the intensity and volume of my workouts based on how I’m feeling on any given day. This adaptive approach helps me manage my MS symptoms while still pushing forward in my training.

In summary, my training is a careful blend of eccentric overload for strength and injury prevention, combined with skill-specific climbing training for technical proficiency and endurance. This balanced approach allows me to continue progressing towards my mountaineering goals while managing my health effectively.

Q: Everything you continue to accomplish is sure to inspire many of our readers to emulate your training. Can you share a basic flywheel strength training routine for aspiring climbers?

A: Absolutely, it’s inspiring to know that my journey can motivate others. For those aspiring to improve their climbing strength through flywheel training, here’s a basic routine that focuses on key areas crucial for mountaineers. Remember, flywheel training, particularly using a device like the kBox4, allows for a high degree of control over eccentric loading, which is great for building strength and improving muscular control.

Basic Flywheel Strength Training Routine for Climbers:


Pre-ruck Activation Drills: 5-10 minutes of light exercises to activate the core and leg muscles. Include exercises like sports squats, zercher squats, RDLs, hamstring curls, and hip flexion.

Eccentric Squats

Purpose: Build leg strength and control, crucial for ascending and carrying loads.
Perform 3-4 sets of 8-10 reps, focusing on a slow and controlled eccentric (lowering) phase.

Eccentric Overload Calf Raises

Purpose: Strengthen calves for improved endurance and stability on uneven terrain and resiliency for load carriage.
3-4 sets of 10-12 reps with emphasis on the lowering phase.

Eccentric Overload Bent Over Rows

Purpose: Strengthen upper body and back, essential for load carriage.
Use the flywheel for resistance. Perform 3-4 sets of as many reps as possible, focusing on a slow lowering phase. Change up the grip for variation.

Core Rotations

Purpose: Strengthen the core muscles, important for climbing movements and load carrying.
3-4 sets of 12-15 reps on each side, maintaining a controlled motion. I use a towel directly on the carabiner and go low-high as I’m rotating. When fatigued, extra assistance from your legs is a nice variation.


Purpose: Build overall strength, particularly in the back and hamstrings.
Perform 5+ sets of 2-5 “working” reps, with a focus on maintaining good form. Don’t count your first few reps used to get the wheel moving. This is where you can add on as many discs as you can tolerate, it’s important to also load your central nervous system (CNS).

Cool Down

Stretching: Spend 15-20 minutes stretching all major muscle groups, with a focus on flexibility. During my wife’s pregnancy, we did the Pliability pre-natal yoga together. As odd as it sounds, this focused heavily on hips and core and I recommend you give it a try before being a hater!

Key Points to Remember:

  • Control: Flywheel training allows for a great deal of eccentric load control. Pay attention to the eccentric phase of each exercise, as this is where a lot of the strength-building occurs.
  • Progression: Start with a resistance level that allows you to maintain good form. Gradually increase as you get stronger. Remember, eccentric training can cause the most adaptation, which means it needs greater recovery.
  • Recovery: Ensure adequate rest between sets and training sessions. Flywheel training can be intense, so recovery is crucial.
  • Adaptability: Adjust the workout to your current fitness level and climbing goals. If you have specific weaknesses or are training for a specific type of climb, tailor your routine accordingly.
  • Safety: Especially for those with health conditions like MS, it’s important to listen to your body and consult with a healthcare team or a trained coach to ensure the training is appropriate for you.

This basic routine provides a solid foundation for building the strength and control needed for climbing. As with any training program, consistency and proper form are key to seeing improvements. I highly recommend you team up with someone who can adequately assess your needs and custom-tailor a program to set you up for success.

Q: I know that you mentioned that during your trip to Denali, the sherpas and guides told you on day eight that they would not let you continue the climb. How did that feel and do you feel that it is a stigma with your condition that people would rather be on the safe side instead of listening to you when it comes to setting limits?

A: Facing the decision of the guides on Denali was a complex and emotionally challenging experience. On one hand, their decision was rooted in a deep concern for safety – a paramount aspect in any high-altitude expedition. Mountaineering inherently carries risks, and the role of an experienced mountain guide is to mitigate these risks as much as possible, for everyone in the team. Their decision, although tough, was made with the group’s safety in mind.

On the other hand, as an individual living with multiple sclerosis (MS), it’s natural to feel a sense of disappointment and frustration when external limitations are imposed, especially when you feel capable of continuing. To this day, I have not been able to find my mental barrier, I’m a combat veteran and Recon Marine so I’ve certainly been tested. It’s a delicate balance between proving one’s capabilities and acknowledging the genuine concerns others may have about your condition.

While I understand their caution, it’s also important for individuals with conditions like MS to be heard and to have their self-assessment of their abilities considered. The reality is that I’m not the athlete I used to be, but I’ve developed mental and physical strategies to deal with losing my step. Being slower than others isn’t quitting, especially when you’re slower and still able to keep a big smile on your face! My personal goal is to love every minute I get to spend on the mountain and have others around me notice.

“This experience does touch upon a broader issue – the stigma and preconceived notions about what people with MS, or any chronic condition, can and cannot do. It’s a reminder of the ongoing challenge to break down these barriers and change perceptions.”


Every individual with MS experiences it differently, and their abilities can vary widely. It’s crucial for guides, and even society at large, to recognize this diversity and engage in open, empathetic dialogues about capabilities and limits.

However, it’s also a learning opportunity for me. It underscores the importance of clear communication and building a mutual understanding with guides and team members about my condition, my capabilities, and the specific challenges I might face. It’s about creating a balance where safety is paramount, but personal limits are set by a combination of self-awareness and mutual respect.

In summary, while the decision on Denali was disheartening, it also reinforces the importance of advocacy, education, and dialogue about living with MS in extreme conditions. It’s about continuously working towards a world where decisions are made based on individual assessments and collaborative understanding, rather than assumptions or stigma.

Q: What have you learned from these experiences when it comes to your training specifically for climbing and recovery?
