Builds shoulder strength through alternating front raises, challenging balance and core stability.
Last updated
The alternate front raise mainly works your shoulders, with your abs supporting the movement.
Fill both AguaForce weights to about 1–3 lb each, using the molded fill lines. Start at the low end if you're new to strength training, and pick a level where the last few reps feel hard but your form stays clean. When that gets easy, add about half a cup of water, roughly a quarter pound.
Aim for 3 sets of 10–12 reps per arm, resting 45–60 seconds between sets. The CDC recommends muscle-strengthening activity at least 2 days a week, so 2–3 non-consecutive days is a good target.
