The deadlift is a compound exercise with a handful of helpful variations. For this leg day, you take on the stiff-legged deadlift, which forces more of the emphasis onto your hamstrings. Don't try to lift as much as you would doing a traditional deadlift.
The remaining exercises in this leg day follow the same path we've been treading for the last six weeks: high reps with method variations. Those high reps will help you get cut and the methods will help direct your body toward failure. "The last three or four reps is what makes the muscle grow," Arnold says. "That's what most people lack, having the guts to go on and just say they'll go through the pain no matter what happens."
So, ask yourself: Do I have the guts? Your answer to that question will lead you down one of two very different-looking paths. Don't answer the question here. Answer it with every rep you do.
