- The InStride POP Fitness Cycle from Stamina Products is so unique and cool. I can sit in my favorite chair, sit on the couch, watch T.V. and pedal away. It works my calves, my thighs, my glutes. Gets my heart rate up and gets blood flowing in my legs. And it's so lightweight I can just place it on the table, work out my shoulders and my arms. It's great for toning and mobility. I just twist the knob to my desired tension for my workout. The textured pedals and straps keep my feet secure on the pedals so I can focus on something else. One of the great things about the POP Cycle is that it comes outta the box and is ready to use in under 30 seconds. All I have to do is unfold the legs, screw in the tension knob and I'm ready to exercise. When I'm not using it, I fold it up and store it out of the way. Although with three awesome color options, you may wanna leave it out to show it off.
