    Great alternative to weights

    I needed a home workout as I did not have any time to visit a gym , been there done that. Time is very precious having a family now. I scoured the internet for things that weren’t weights. Weights take up too much space since I don’t have a garage or extra room. I was skeptical honestly about bands but the videos for muscle building are very good and you can tell lots of research was done for the styles of exercises. I am on my 3rd month and seeing great results. Huge fan of this company and what they’re doing with fitness. My bought my girl the fat burner program and she’s losing weight too feeling great looking great. Thank you for making it fun and easy to use.

    I can feel this resistance building and exhausting my muscles so differently and better than straight free weight work. I’m encouraged and excited to see results

    Muscle building bundle

    It’s great way better than free weights or weight equipment. I really get a good pump from them.

    Resistance bands

    Amazing. Been using almost every day & the possibilities are endless. Just wish I had more time to use them.

    Good Product

    I like that the resistance is highest at full extension/contraction. With conventional weights if you don't do a lot of stretching you tend to feel a tightening up and over time lose flexibility. I don't get that feeling with bands.
