Pull up assistance

I’m thinking of purchasing a pull-up band.. can I use my bodylastics bands to assist with pull ups in place of it? I used to be able to do them on my own but after surgery I now have to use the assistance bar at gym but I wanted in between weight on assistance. It’s either too much help or not enough. Thanks :) 

Absolutely. Just use the straps and secure them around your thighs or feet and wrap the bands around the upper bar.
