If you’re serious about becoming stronger, why pay for dumbbell sets that will limit your potential and your range of productive exercises? Each StaminaX Versa-Bell 50 lb. Dumbbell offers nine weights in one, shattering the limitations that come with a single-weight dumbbell. Simple Weight Adjustments Perfect for your home, the StaminaX Versa-Bell dumbbell provides all the flexibility and benefits of nine separate dumbbells yet requires the space of just one, saving both space and money. Even better, the Versa-Bell is built for convenience and durability. The simple-adjust dial mechanism is made with rugged material and lets you switch among the nine weight settings in just a few seconds - eliminating the annoying interruptions needed to replace weights on the old-style dumbbells. Called “Versa” for a Reason Not only is the weight of the dumbbell versatile, but the exercises are also limitless. Your core, upper and lower body can be targeted simultaneously or isolated depending on your routine-it’s up to you. Consider just a few of the isolating exercises that Stamina personnel find especially effective: Dumbbell Bench Press - Strengthen your pectorals, triceps and deltoids (shoulders) Alternated Biceps Curl - Target your biceps Shoulder Press - Work your deltoids and triceps Kneeling One Arm Row - Build your lats Stationary Lunge - Do a complete lower-body workout, including the glutes, quadriceps, and calves Calf Raises - Increase calf strength.
