Arm exercise using water weights

Water weights are foam barbells that create resistance under water. Start with the arms at the sides. Grip the bars of the water weights with the palms facing up. Raise the forearms to the level of the water, keeping the elbows close to the body and the wrists straight.

Then turn the barbells over so that the palms of the hands face the bottom of the pool. Push the hands down until the arms are straight again. Repeat 12 to 15 times or until you're tired.
