Trying to be careful with COVID but couldnÕt get that gym pump until REX. Good looking out.

I am 72 years old living in a small apartment. This has been such a fun way to exercise my arms and legs at the same time.

My son got this for me because I could no longer go to the gym. I have been using it every day and it is so easy to use.

I use this for squats every single day and having the 4 bands makes it so easy and a great workout. Recommend for anyone that does squats.
