Define what means harder.
What is harder:
- Pistol with a heavy enough weight.
- barbell squat with enough weight (I never squatted more than 130kg with a barbell - 140kg for me is harder than a pistol).
If you stick to bodyweight, there is an alternative to pistol that is quite hard (even though it looks easy) and more friendly for your knees. Get your feet aligned, heels on the floor, and squat. It is more friendly because the knee does not go inside like it can in a pistol. I did not invent this, it was shown to me by Alexey Sénart, senior instructor. I could do one rep, but it was not a walk in the park like I imagined!
