Leg squats work out your buttocks, thighs, calves, hamstrings and lower back. They also involve the core as a stabilizer. This efficiency makes them popular as their own exercise, or as part of a broader workout program. This article is about body weight squats.

Health resource website NutriStrategy provides information for calories burned in different activities. According to NutriStrategy, a 155-lb. person doing leg squats or other calisthenics burns about 125 calories in a 30-minute session.
How intensely you do an exercise has a big effect on how many calories you burn. The same person working out for the same length of time at a vigorous pace would burn 280 calories -- more than twice as many as at a moderate pace. In addition, adding a jump to the exercise sequence - a jump squat - would increase calorie burn per repetition.
Aside from intensity, your body weight plays the biggest role in how many calories you burn at an exercise. A 205-lb. person doing the same moderate half hour of leg squats would burn 163 calories. A 130-lb. person would burn only 103.
