10 Handstand Pushups (sub elevated/piked pushups)
80 Sit Ups
160 Air Squats
If you don't have a pullup bar, improvise. Use a towel to do a "ring row" style movement over a banister or something sturdy. For situps, make sure your knees fall open to either side, so you are recruiting your entire abdominals, and make sure every squat goes below parallel. If you don't have a med ball to squat to, find something that is about 18" and squat to that.
