Competitive triathletes are required to be strong across three disciplines, swimming, cycling and running. This demands that their training be efficient, that they are able to achieve optimal results from the time they spend training for each leg of an event.

The kBox caters to these needs by providing a multi-exercise device that can provide general strengthening as well as sport specific drills.


Triathletes are unique athletes in that they require the lower body strength of an Olympic cyclist, the endurance of a long-distance runner as well as the upper body strength of an elite swimmer.

Runners can suffer from overuse injuries that can occur with many kilometres pounding the pavement. The kBox offers a low impact alternative with the same strength and endurance advantages. The same benefit can be gained by swimmers during dry land flywheel training, avoiding such overuse injuries such as shoulder impingement, rotator cuff tendonitis and bursitis.

Flywheel training provides a great option for strengthening the muscles of the rotator cuff, vital for swimming as well as training both heavy compound lifts for explosive leg strength and isolated muscle drills. The versatility of having a unit which is portable enough to travel between training and competition venues or simply to use at home, makes it an ideal training tool.

The compact size of the kBox makes it the perfect option to fit in an athlete’s home. Whether it be in a home gym or the living room, it provides an opportunity for extra strength training that can be done in between long sessions on the bike, the road or in the pool.

The kBox can be used for general strength and conditioning training or rehabilitation as well as during pre-event warm up.

By incorporating flywheel training with the kBox to perform a small but significant amount of strength and conditioning, triathletes are able to complement their main training load and reap the benefits without placing further strain on their bodies.


The kBox provides a training unit that can improve endurance and specifically core strength, a quality that is especially important in order to maintain correct posture on a bike, which can worsen when fatigued. It can target explosive speed for transitions and overtaking other competitors and help to improve efficiency of movement and decrease fatigue.

Another well known advantage of strength training is injury prevention, especially for joints and tendons that are prone to overuse injuries e.g. ankles and knees. By increasing the strength of the quadriceps, hamstrings and calf muscles (gastrocnemius and soleus) the tendons are able to withstand the repetitive strain involved in training for and competing in endurance events.

Exercises can also be tailored to improve pelvic stability through glute activation which can correct leg alignment and running pattern.
