Diesel, if you do stiff legged because you want to build your hamstrings, you shouldn't go too heavy. If you go too heavy, you won't even feel the hamstrings being worked. Heavy stiff legged are awesome for your back development, that has to be said.
So if you are doing them on leg-day, I would recommend 2 sets of 20 good reps with perfect form. Just make sure you don't lift too heavy. Do them after some heavy squats and you will feel a burn in your hams like you never felt them burn before. |
