Fitness Focus: Triceps

• Sit on the floor with your legs and feet pressed together, knees bent and feet flat on the floor.
• Place your hands about a foot behind your butt, palms shoulder-distance apart, fingers pointing toward your butt. Straighten your arms to raise your butt off the floor.
• Bend your left elbow and lower your butt as close to the floor as possible without actually touching it.
• Straighten your left arm; repeat, this time bending right arm.
• Alternate sides for 60 seconds.
• To make the move a little easier, try spreading your legs up to 2 feet apart.
