If you stop and really focus on your shoulders right now, how do they feel? Nice and relaxed? Or full of stress and tension? Most of us experience shoulder pain, because our posture isn’t always what’s on our mind while sitting at our desk, in traffic, or on the couch binging our favorite show.

A sure-fire way to break through a strength plateau is to increase your range of motion. One of the most overlooked and underrated methods to do that is through isometric training. First discovered in the 1950s by researchers Hettinger and Muller, isometrics is where your joint angle and muscle length stay the same during muscle contraction.

If you’re ready for the next level of fitness, a full-body isometric workout routine is the way to go. With an intense workout that hits all the right spots, you can get one of the most powerful workouts of your life in just a couple of minutes. All you need is an Activ5 and the motivation to give it your all.

Activ5 utilizes isometrics to act as a highly effective and versatile addition to any strength-training or exercise regimen. To really understand how Activ5 works, it’s helpful to review the foundational science behind muscle activity.
