Resistance band training
Resistance bands and tubing are one of the cheapest, yet most flexible items of fitness equipment available. They can be used as assistance equipment when learning advanced movements like the planche, to adding progressive resistance to weight training exercises and even in developing speed and acceleration skills through ballistic running drills.
Add handles to your resistance bands to make them ultra-portable gyms in their own right, allowing for a host of total-body exercises such as band push-ups, curls, and squats to name but a few.
