Please choose from our six different resistance/tension levels. To help you select the best band for your application, we have included a tension guide and pull-up guide in the images to the left. We have also included a quick sampling of exercises that can be performed using Serious Steel Bands! YOU ARE CURRENTLY VIEWING OUR #1 (PURPLE) BAND. This band measures " wide, 4.5 mm thick and 41" in length. It offers resistance from 5-35 lbs. This band is a great beginner band for resistance exercises that range from bicep curls, squats or even overhead shoulder press. The #1 is also great if you are looking to do speed work by adding the band to your bench press, deadlift or squats. MULTIPLE BANDS: Do you think you need a #4 band, but concerned it may be too much tension? You can purchase multiple smaller bands to equal the tension of heavier bands. Try the #2 & #3 instead of the #5 or try the #3 & #1 instead of the #4 band. Combining multiple sizes gives you more levels of tension because you can use them individually or you can use them at the same time. PULL-UPS: Serious Steel Bands are a perfect tool to help you with your pull ups, dips or muscle-ups. Take a quick look at the Pull-Up Guide image to your left to get an idea of the best band for you. Choose a band based on your bodyweight and the current number of unassisted repetitions you can complete. One important thing to remember about using bands for pull-up assistance is that you can secure the band under your feet or under your knee for different levels of assistance. FREE Pull-up and Band Starter e-Guide with every band purchase!! Pull-up and Starter e-Guide are emailed after shipment.
