1-leg deadliftGreat uni-lateral lower body exercise here.
Grab the barbell with both hands like you were about to do a deadlift. Now barely lift one leg off the ground.
Start the movement by lifting the heel up and back while simultaneously lowering the bar. The key here is to keep your back set and not "reach" for the ground.
It is more important to get a good stretch in the hamstring and keep a flat back than it is to touch the ground with the plates. If it does great.......if it doesn't and you don't have the flexibility to go that far down then just change direction and repeat.
