Can I use cloth resistance band around my legs doing the moving version. I have multiple bands with low to high resistance.

I signed up for 2 week trial yesterday.  I haven’t found where I can create a password.  Also, when I attempted to get the app, I was asked for a password to an old email I haven’t used in years.   Also, I am not new to working out and want to make sure I’m starting with the right workouts.  I haven’t done consistent strength training for several months.  I’m almost 62, female, and am back to using 5-10 pound dumbbells for most upper body work.  More for back exercises.  I’m not overweight, but have excess body fat and need to tone and, hopefully help my cellulite problem.
