The Kiefer Water Workout Dumbbells turn the pool into a gym

Kiefer Water Resistance Dumbbell

When we’re young, going to the pool means getting to jump into the water, overcoming fears of the high dive, and going down the big slide. The older you get, a pool means chillingly cold water, and an impact-free way of working out. If you are fortunate enough to be near or have access to an indoor pool, you may as well skip working out on land altogether.

While treading water and resistance workouts will do just fine, you’ll eventually reach a point where you’ll want some accessories to make your routine more challenging. You could be super awesome and carry a cinder block while walking along the bottom of theĀ deep end, but until you work up to that point, these Kiefer Water Workout Dumbbells should do just fine. These will help your biceps, triceps, shoulders, and core, because it will take everything you have to move these for more than a minute straight.

These are made to be medium resistance at 6 inches in diameter on the ends, and there are more challenging levels if you start reaching super saiyan levels of strength underwater. This is a great way to handle therapy, fitness, or aerobics programs for those that don’t want to jar their joints when working out. These come in yellow and blue and are sold in a pair for $27.45. Summer may be gone, but the lucky ducks near a heated pool would likely get decent use out of these.
