5-Move Arm and Ab Workout

These moves tighten and tone two areas you’ll want to show off when you hit the beach. Plus, your core will get stronger, giving you better balance. Mahri Relin, founder of Body Conceptions studio in New York City, created this workout exclusively for SELF (based on her hot new Power Sculpt class).

You’ll Need: a 2- to 3-pound weight.

Do: one set of these moves three times a week. For a greater challenge, add 30 seconds of cardio, like high knees or jumping jacks, after each move.

Plus: See the moves in action.
