(What) One of the exercises for everyone but especially anyone that runs is the single leg RDL with knee-knuts. (Why?) Because it hits the posterior chain and the hamstrings in a way that makes way more sense than a machine leg curl and a must do for developing leg balance, coordination and range of motion... oh if your trying to get faster this is must-do.(How) 1. Keep weight centered on mid-foot to heel. Make sure the lifting leg lifts at exactly same rate as torso lowers, in fact that leg should act as if it's being lifted up and back. 2. Sit that loaded back as if your doing a deadlift on one leg. Lower weight as close to your leg as possible, as if your dropping the weight directly onto your foot. 3. HOW LOW YOU GO DOES'NT MATTER if the the lifting leg isn't extension of the torso, like a pendulum. 4. For speed/power, I add a "Knee-Knut" at the end...I tell Josh, once he reaches point where he's maxed out the loaded hammy, FIRE! the hips through so other knee jams to knee someone tall in the nuts. #samsays #exerciseoftheday #samfitnyc #instagramfitness #MovementMonday #MondayMobility #LegDay #SpeedBreeders #FastFolk #StayFastMyFriends #WeRunThis #SpeedofLife #SprintTraining #FortuneFavorstheFast (at Titan Fitness Studios)
