In the past few months, we have covered plenty of cool resistance bands and training tools here. The Tension Toner is another tool that lets you activate more muscles and burn more calories. It has a resistance band that runs through the tubing. The device has two directions of resistance.
You can add vertical resistance by resistance bands to do even more with this tool. Attach the device to your door to get some training done at home. According to the developer, over 200 exercises are supported. Tension Toner is currently on Kickstarter.
