Product Description Save Space, Build Strength With the Stamina Adjustable Kettle Versa-Bell, there is no need for entire kettlebell sets. One Versa-Bell replaces an entire set of conventional kettlebells or dumbell sets at a fraction of the cost and takes up very little storage space because the weights can be stored either inside the kettlebell or on the square base pad. The kettlebells adjustable weight- four pound increments, ranging from 16 to 36 pounds- let you customize your strength training intensity just as an entire set of kettlebells would. There's No Isolation with Kettlebells Kettlebell workouts burn body fat, build strength, increase joint mobility and even improve cardio fitness. The round part of the adjustable kettlebell is the main weight, and when you hold the handle it displaces that weight away from your body. This makes the physics of lifting different than with regular small weights or dumbbells. When you lift, lower, or swing the kettlebell, your stabilizing muscles engage so your entire body is working, including your core muscles. There is no such thing as isolating a muscle with kettlebell exercises.
