Come down to floor or mat with knees together and sit on feet. Holding dumbbells, bring hands to tops of thighs, palms facing down. Take a deep breath in and, exhaling, slowly (an inch at a time) come up onto knees, raising arms in front of you and lifting dumbbells toward ceiling. Using core strength, slowly lower back down (an inch at a time) and return to starting position. Repeat 5 times, moving slowly and with control.
