About the kBox

Train Up To Your Potential

With the kBox and kPulley, instead of a fixed load determined by gravity when lifting weights, you work against the variable inertia of heavy steel flywheels determined by the effort and energy you unleash into the device.

Engage Every Muscle

These training devices are truly versatile and serve multiple purposes, allowing you to engage your upper body, core and lower body with a wide variety of exercises.

Keep The Gym Nearby

It is completely portable and easy for anyone to carry or stove away.

Get Real-Time Feedback

Its kMeter app-based wireless feedback system can be used to measure and save actual power output and more.

Switching between drills and users is quick and hassle-free.

Silent

The kBox practically doesn’t emit any sound at all.

Training at home, here's a creative and thoughtful unsystematic repetition format on the #kBox4 by Joel Smith, MS, CSCS and NCAA Division I Strength Coach @justflysports. Each repetition is performed differently than the previous one but all with the potential of maximum resistance, giving an overall unique stimuli. 💡

Workouts have been moved to my apartment, which gave me a great chance to apply some concepts that @tyleryearby and @bbaperformance taught me in a recent podcast episode.
⬇️.
Today (and for a good while) the vast majority of my strength training (here on the @go_exxentric kbox4) was done in a “rep without rep” format. In this scenario, each rep is done in a slightly different manner. The rhythm and fast moving action of the kBox makes this work particularly “alive” in this format. #acceleration #sprinting #sprint #tracknation #track #100m #sportsperformance #biomechanics #motorlearning #foottraining #40yarddashtraining #combinetraining #athleticperformance #athlete #tracklife #strengthandconditioning #speedtraining #periodization #fitness #jumptraining #functionaltraining

Here's what a training session at home could look like guided by the Flywheel Training App, nicely demonstrated on the #kBox4 by @sarabackfitness with a good reminder to keep our hands and equipment disinfected. 💪

Training to complete The Swedish 100 Miles Challenge, ultrarunner @patrikmardh shares his program with us. 🏃‍♂️
.
Could you tell us about your training program? ”I train for several different 100 miles races both in Sweden and abroad. Every day starts with running at 5 am, usually 10-20 km, but sometimes longer. After that I have breakfast before transportation running to work. I also try to do some body weight training every day."
.
How far do you run each week, and how many sessions do you manage to get done on your #kBox4? "Each week consists of about 150-200 km of running during early mornings and transportation running to work, meetings, events and my kids' activities. I usually train on the kBox 3-4 times per week. It's an outstanding tool and compliment to my running."
.
Which are your focus exercises on the kBox? ”I do almost full-body workout with different exercises. I usually do 6 different exercises, with 3 sets and 10 reps each. The exercises I do are triceps, split squat, squat, lateral squat, biceps curl and rows."
.
Do you have three favorite exercises? ”My three favorites are squat, lateral squat, biceps curl." Thanks for sharing Patrik, and best of luck with #TheSwedish100MilesChallenge! 💪
