I feel these workouts help with overall leg strength and injury prevention. Am I wrong in this assumption?
Second this! I’ve been doing the floor work from Boss Bands Legs and Core, Butts and Guts and STS 2.0 Body Parts Legs, plus foam rolling, STS Mobility 1&2, etc and my janky left hip feels loads better. Combine that with a really good leg workout (STS 2.0 Body Parts Legs, for example) and it hits all the targets — strength, mobility, rehab, stretching, and rest. Works amazingly well.Not Cathe here either, however Cathe emphasized she would select the most effective exercises for developing strength when planning this series. Maybe in the new Killer Legs there will be more endurance-based excercises. I agree with you that floor/mat leg exercises can help with strength and injury prevention and rehabilitation. When I'm nursing or rehabbing the lower body, I include lots of Cathe's floor/mat exercises piece-mealed from various LB workouts.
