The Serius Strap®, gives you the most advanced features in Suspension Conditioning.

The patented, Rotating, Multi-Position Handles featured on the Original Serius Strap Suspension Strap are the most effective fitness handle on the market, here's why:

Every SERIUS STRAP includes two MarV® multi-position, rotating Fitness Handles. These handles are the most technically advanced designs in the exercise or physical therapy industry, and the only body weight trainer you will find them on is the SERIUS STRAP.

What is a MarV®?

MarV®, which stands for "Multi-Angular Rotating Vector," was designed by Colorado based Physical Therapist, David Berman, MS, PT, COMT, CSCS, who wanted a more effective method of resistance exercise for his patients. Not only is it more comfortable, safe, and reliable--it is more effective. MarV Handles can be found in physical therapy clinics around the world, and now for the first time in the exercise market - on the SERIUS STRAP.

Why is the MarV Handle so valuable to you?
First and most importantly, it gives you a significantly better exercise result with less effort, and that’s what you’re after, isn’t it?

MarV Handles on the SERIUS STRAP give you multiple, distinctly different, easy to use grip positions for each exercise. This allows you to choose the grip that’s most comfortable, that will target the muscles you wish to target, reduce your body lean while maintaining the maximum resistance, and get more results in less time.

	Channel Grip: University studies show the MarV 3-Position Handle in the Channel Grip position, provides 30% more muscle activation than a traditional handle--that's a significant improvement! The Channel Grip position, a patent pending feature of the MarV Handle, also gives you a level of joint stabilization never offered before in an upper body resistance product. Now you get the most sought after benefits of core training in your upper body workouts.
	Natural Grip: When you use the Natural Grip position, you reduce the wrist’s involvement in an exercise. This allows you to accurately target muscles in the forearm, bicep, and shoulder. You can also duplicate exercises you can do on the triceps ropes, cambered curl bars, and cambered grips on weight machines in the gym (cambered means the wrist is positioned at an angle instead of horizontal or thumb up).
	Stirrup Grip: You can choose the familiar Stirrup Grip for any of the exercises you can do on the SERIUS STRAP. While the handle is in the Stirrup grip position, you can manually rotate the handle to duplicate a Vertical or cambered grip quickly and easily. This feature is so cool, you’re going to love it!
