Water weights are foam barbells that create resistance under water. Start with your arms at your sides. Grip the bars of the water weights with your palms facing up. Raise your forearms to the level of the water, keeping your elbows close to your body and your wrists straight.
Then turn the barbells over so that the palms of your hands face the bottom of the pool. Push your hands down until your arms are straight again. Repeat 12 to 15 times or until you're fatigued.
