Reverse sled drags are a great bang-for-your-buck exercise that serves as both a rehabilitative tool and a muscle/strength builder. They burn like crazy while you're doing them, but since there's no eccentric component, they don't leave you crippled with soreness so you can do them frequently, several times per week.
In this variation, row the sled toward you, then keep your elbows pulled down and back. Keep your hands pinned to your sides as you walk backwards.
Two of the hardest things about competing are sending in the entry fee for a competition and then not pulling out the last few weeks. Some of you don't compete and are just training for self-actualization, self-esteem, and to be healthier and more whole in your daily interactions in the journey we call a life experience.
Lately there's been much discussion about whether it's more beneficial to do total body training (TBT) or some version of a split system where parts of the body are separated for different workouts.
