Free weights are great for building stamina, but most home gyms aren't equipped with all the poundages needed in endurance workouts. Our stamina exercise weights make it easy–even if space is limited. One pair of stamina dumbells from Brookstone can replace a dozen or more traditional bells, letting you change weight with a simple twist. Move quickly between exercises for cardio fitness, or do max poundages for strength training. Plus adjustable stamina weights help friends or family with varied fitness levels work out together. It's a fun way to stay motivated and fit.
