I would like to know if there is another exercise I could do in place of chin ups. Don't have the space for equipment, the band doesn't work, and am not sure the pull up bar in door frame will work.
I didn't feel that the band was a challenging enough substitute for the chin ups. So I purchased a set of 3 long resistance tubing from Walmart. It allows you to attach multiple resistance tubes to the handles. Last night I attached the medium and heavy tubing and did the lat pulldowns with that - what i big difference!
