Hey I have been hanging for almost 2 months now and am looking for a change of pace. I have been hanging SD the entire time, started with 5 pounds and was only able to handle about 5 min sets, to now where I can hang 8 pounds for a pretty easy 20 min. My question is how do I switch up the angles. I read about BTC or stretching down and to the left or the right how do I achieve those angles. Thanks for any responses much appreicated!
