FAQ Guide for Your Ativafit Experience
The Martian's 10 weight levels (5-50 lbs) support complete full-body training at home. You can perform all major exercises: chest press, shoulder press, rows, squats, deadlifts, lunges, curls, and core movements. The Quick DialTech system lets you easily switch between light weights for isolation exercises (lateral raises at 10 lbs) and heavy weights for compound movements (squats at 50 lbs) in the same workout. One pair replaces 10 traditional dumbbell pairs, giving you gym-level versatility in your home.

Ativafit adjustable dumbbells use a precision DialTech system to change resistance instantly. When the dumbbell is docked in its base, simply hold the safety button and rotate the dial to your desired weight. This engages a specialized 10-point internal locking mechanism that secures the chosen steel plates. Once you lift the handle, the unselected plates remain safely in the tray. It’s a seamless way to access 10 different weight levels—from 5 to 50 lbs—using just one pair of handles.
Minimal space required: Each Martian dumbbell with its tray measures 16.7"L × 8.2"W × 7.7"H. A complete pair needs just 3 feet of floor space.

Storage flexibility: The included trays serve as the base—no rack needed. Fits perfectly in apartments, spare bedrooms, closets, or garage gyms. You can also add our Atlas Stand for elevated, organized storage.
