How to do: Dumbbell Squat

Step-by-step instructions

1. 1Stand up straight while holding a dumbbell on each hand (palms facing the side of your legs).
2. 2Position your legs using a shoulder width medium stance with the toes slightly pointed out. Keep your head up at all times as looking down will get you off balance and also maintain a straight back. This will be your starting position. Note: For the purposes of this discussion we will use the medium stance described above which targets overall development; however you can choose any of the three stances discussed in the foot stances section.
3. 3Begin to slowly lower your torso by bending the knees as you maintain a straight posture with the head up. Continue down until your thighs are parallel to the floor. Tip: If you performed the exercise correctly, the front of the knees should make an imaginary straight line with the toes that is perpendicular to the front. If your knees are past that imaginary line (if they are past your toes) then you are placing undue stress on the knee and the exercise has been performed incorrectly.
4. 4Begin to raise your torso as you exhale by pushing the floor with the heel of your foot mainly as you straighten the legs again and go back to the starting position.
5. 5Repeat for the recommended amount of repetitions.
