I approach my training with a strong focus on balancing endurance, strength, and recovery, especially considering my background and the challenges of MS. Here’s how I program my workouts week-to-week to stay prepared for my upcoming climb on Mt. Elbrus:

  1. Focus on Cardio: Since cardio has always been my weakness, I prioritize it by conducting fasted cardio sessions every morning. These sessions typically last between 45 to 75 minutes on the Air Bike. I find this machine to be effective for building my cardiovascular endurance while being low-impact, which is crucial given my condition. I maintain consistency with only one or two rest days per week to help retain adaptations more effectively than traditional athletes.
  2. Structured Conditioning: In the afternoons, I incorporate a variety of conditioning workouts. Currently, I’m in an aerobic block, alternating between contralateral circuits and escalating density training (EDT) sessions that last about 45 to 60 minutes. This approach allows me to build functional strength and endurance efficiently.
  3. Eccentric Training Blocks: Leveraging the Triphasic training model has been a smart move for me, especially since descending is often the most challenging phase of a climb. I dedicate entire blocks to eccentric training to enhance my control and strength during descents. This type of training improves my muscle resilience and prepares me for the demands of descending rugged terrain.
  4. Weighted Step-Ups and Rucking: I incorporate long weighted step-up sessions twice a week, generally on an air bike rest day, to simulate the climbing experience and strengthen my legs for both the ascent and descent. I get added adaptation by only allowing myself to nasal breathe during these sessions. Given my background as a Recon Marine, rucking comes naturally to me, so I focus on improving the adaptations for load carriage instead. I train with a weighted vest or a sandbag pack during circuits to condition my upper back and shoulders for prolonged carrying, which is essential for extended climbing sessions.
  5. Collaboration with Experts: I’m fortunate to have a conditioning advisor like Dr. Mike T. Nelson, whose expertise adds tremendous value to my training. His knowledge, especially from co-authoring Triphasic Training II, complements my self-programmed strength training and ensures that my workouts are effective and tailored to my needs.
  6. Weekly Overview: My typical week consists of morning fasted cardio sessions from Monday to Saturday, followed by afternoon strength and conditioning workouts. This disciplined routine helps me build the endurance and strength necessary for my upcoming ascent while allowing for adequate recovery.

By focusing on these key components—maintaining consistent cardio, leveraging eccentric training, incorporating weighted conditioning, and working with knowledgeable mentors—I’m setting myself up for success on Mt. Elbrus. My structured approach not only prepares me physically but also ensures that I’m effectively managing the challenges that come with MS. I’m looking forward to my training and the climb ahead!

  • Do you feel that the kBox gives you the opportunities to train hard and program adequate room for recovery in your training?


Absolutely, the kBox has been instrumental in allowing me to train hard while also incorporating adequate recovery into my regimen. Initially, I relied on the kBox as the primary component of my workouts, but I’ve evolved my approach to use it more like “seasoning” to enhance other lifts and maximize the adaptations I can achieve from each session.

By integrating the Kbox into my training, I can focus on explosive movements without the same impact stresses that traditional plyometrics might impose, which is particularly beneficial given my MS. For instance, I’ve transformed a Triphasic French contrast circuit that allows me to blend heavy strength training with explosive movements effectively. I start with heavy SSB squats to build strength, then transition immediately to the Kbox for light, explosive sport squats. This method not only helps me maintain power but also ensures that I’m not overloading my joints while still pushing my limits.

Following the Kbox squats, I incorporate a loaded jump, which further enhances my explosive capacity, and I finish off with band-accelerated jumps. This sequence allows for high-intensity training while also considering my recovery needs, as the Kbox facilitates gentle, controlled movements that help prevent overexertion and injury.

This approach has significantly improved my overall performance, providing a balanced training experience that challenges me while still respecting my body’s limitations. The kBox has truly become a versatile tool in my arsenal, enabling me to wring out as many adaptations as possible from each exercise and session, all while allowing for the necessary recovery that is crucial for my ongoing climbing endeavors.

  • Has the kBox given you opportunities to train in ways that might not be possible for you or other people with MS  in a typical commercial gym setting?


Yes, the kBox has opened up training opportunities that might not be feasible in a typical commercial gym setting, especially for someone with MS. One of the standout features of the kBox is its ability to provide controlled eccentric resistance, which allows me to focus on developing strength without the heavy impact that traditional weights can impose on my joints. This is particularly beneficial for managing the unique challenges that come with MS.

In a commercial gym, the equipment often prioritizes traditional strength training methods, which might not accommodate the specific needs of individuals with MS. For example, high-impact exercises or those requiring extensive stability can be difficult and potentially risky. The kBox, however, allows me to perform explosive movements in a safer and more controlled manner, making it possible to train effectively without the fear of injury.

Additionally, the versatility of the kBox enables me to tailor workouts to my specific needs. I can easily adjust resistance levels and modify exercises to suit my current physical condition. This adaptability is crucial, as it allows me to progress at my own pace while still challenging myself.
