You'll need a set of 5-pound dumbbells. This targets the front of your shoulders, abs, and glutes. Do 8 reps (4 per arm) on each leg.
Single Leg Front Raises. Stand with your feet hip-width apart, holding a 5-pound dumbbell in each hand. Bend your right leg and raise it about 3 inches off the floor. Extend both your arms straight out in front of you at chest height, palms facing down. Keeping your arms straight, raise your left hand above your head and hold for 3 counts then lower it back to your chest height. Repeat with your right arm, continue alternating arm raises until you've done 8 total, 4 reps on each arm. Now switch legs and do 8 more reps standing on your right leg. The single leg dumbbell front raise targets the front of your shoulder as well as your abs and gluts. If balancing on one leg is too hard, you can also do this exercise with both legs on the floor.
