| The narrower the stance, the less the hamstring emphasis. It's not that the olympic stance squats don't hit the hams or glutes but place a bit more emphasis on the quads than anything else. The olympic stance squats really hit a bit of everything from the waist down, so these should be the staple and follow them up with one quad emphasis movement and one posterior chain movement.
I integrate wide stance box squats about every 3-4 weeks from olympic stance squats because they're both useful tools to have in the pocket. And actually, I rotate about half a dozen main leg exercises every week, so I tend not to return to the same movement for 2-3 weeks. |
