Why use a TRX and resistance band for exercise?. By combining a band and TRX. You can create two different types of training styles. That put the nervous system under different levels of shock compared to standard gym weights.
Personally I’ve found better aesthetic, cardiovascular, flexibility and muscle growth. When using a TRX combined with bands within my nomad travel life. Than I ever have from years of time spent in the gym.
Don’t believe me? Give it a go yourself!
