How to do it

1. Stand with feet hip-width apart, arms at your sides, palms facing forward.
2. Slowly step one foot forward, bending at the knee while keeping your back straight.
3. As you step, perform a biceps curl by flexing your elbows and bringing your palms toward your shoulders.
4. Pause briefly, feeling the contraction in your biceps, then return to the starting position.
5. Alternate legs, performing the same steps for each side to complete your set.
