The TITIN FORCE line is patented weighted apparel with form-fitting gel inserts. The gel can be heated or frozen for post-workout recovery, while staying flexible at all temperatures. The gels are evenly distributed across the body, affecting only the muscles and not joints, leading to healthy, regenerative muscle fiber recruitment. The shirt adds 8 lbs of weight but feels like 20 lbs due to dynamic loading, tricking the mind into thinking one is carrying more weight. This causes the body to work harder to recruit muscle fibers which causes muscle regeneration and stronger muscles. From 80 to 400 lbs and in every sport, TITIN"s HyperGravity effect is used to help with strength, agility, vertical jump, and overall fitness. The system is comprised of an inner pocket shirt, outer compression shirt, and gel weights. A double-stitched, moisture-wicking compression shirt locks down the weight while promoting increased blood circulation. The shirts are made of A.M.Y. Polyester antimicrobial fibers and quick dry threads, meaning the shirts wick sweat 4X faster than the leading compression wear, and the shirts neutralize odor and get rid of bacteria on impact. You will never have to wash a unit. The gels have a lifetime warranty and won"t burst, ooze, or change heating or cooling properties after use. TITIN can be used in any workout and will not restrict movement or alter the workout. TITIN is the only gym bag you will ever need. The only question left, is can you keep up?.
