Resistance Bands

Hello šŸ‘‹ Iā€™m wondering if any of you use resistance bands in place of the adjustable dumbbells? I am enjoying the programs, and want to get stronger, but Iā€™m not ready for the investment of adjustable dumbbells. I have some resistances bands and have used them for some of the workouts, but Iā€™m not sure I am doing the exercises correctly using them. Would love to hear your thoughts. Thanks! šŸ˜
