This multitasking move will target your thighs and biceps at the same time.
- Stand with legs wide and toes pointed outward slightly. Hold a pair of dumbbells in your hands with your arms straight and your palms facing down.
- Bend your knees until they are over your ankles while raising arms to just below shoulder height. Arms should be in line with your legs — you should see the weights in your peripheral vision.
- Straighten your legs, and lower your arms simultaneously.
- Complete three sets of 12 to 15 reps.
