Here's a way to make yourself way less comfortable, but way more badass while working out. The TITIN Force is a complete weighted compression system all tucked into a short sleeve shirt. It utilizes a 3-part hyper gravity approach to help boost training efficiency, speed, balance, endurance, and vertical leap.
Fourteen weighted hydro-gel inserts totaling 8 pounds slip into TITIN's 14- pocket inner compression shirt. The inserts distribute evenly over the upper body's large muscle groups, which are then covered by the third element of the hyper gravity system, an outer compression shirt. Effect: snug as a bug in a rug. All girdled and jacked and ready to pump. TITIN says its hydro-gel packs are indestructible, still allow for full mobility during workouts, and serve well as "preloaders" or to warm up before a competition. The inserts can also be heated or frozen for 30 to 45 minutes of therapeutic use.
