Leave a set of 5-8 pound dumbbells next to your desk or kitchen chair. Sit up straight without leaning against the back of the chair. Hold the dumbbells at your side with your belly muscles held tight. As you look straight ahead, inhale and stand up tall. Exhale, and sit back down. Repeat this simple sit and stand (a.k.a. chair squat), 8-12 times/2 or 3 sets. This exercise will help strengthen your butt, thighs and abdominal muscles especially when performed 3-4 days a week. The key to success here is leaving the dumbbells next to your chair at all times. In plain sight! Harder to ignore them!
