Stay Fit Minute #10- Supine Ball Leg Curl

I'm a big believer in incorporating bodyweight exercises into a program, and I encourage the use of free weights and bodyweight movements over machines.
The butt and hamstrings are often a neglected area which must be addressed in order to protect your knees, lower back, and maximize your strength in other movements. My favorite exercise for these muscles is the Glute Hamstring Developer; however, this machine is rare to find in most gyms.

Another great basic exercise for your glutes, hams, and core (which requires minimal equipment) is the lying ball leg curl. As a progression you can try this with one leg as well.
