Our bicep curl isolator promotes proper form while lifting to prevent cheat curls. This unique device helps you cultivate the correct technique and ensures your elbows are always tucked into the right place. With the arms remaining close to the body throughout the workout, our product forces the user to maintain a proper form by isolating the biceps which will only maximize the strength-building benefits of the workout. Our bicep arm blaster stabilizes your arms to isolate your bicep muscles, prevents your arms from flailing or pointing outward during dumbbell and barbell curls. Additionally, our arm blaster has foam padding in two areas. There is foam padding along the back of the strap that supports the neck so it won't dig into your skin or strain your neck adding some comfort to a vigorous workout. There is also foam padding where the back of the arm will rest. This device is lightweight, portable and a good replacement for several curl machines, like the preacher curl or cable curl. Victor Fitness products are built to take your workout to the next level!
