Is anyone using or have they used resistance bands for their workouts as an alternative to weights? I had planned to start the challenge 11-5 but have been delayed in doing so and will start on or about 12-10. I am very limited on equipment but have a nice selection of bodylastic resistance bands (about 300 pounds of total resistance) I have found that if I step back slightly for each phase of a workout, the resistance increases  which simulates the increase in weight per set quite nicely. The delay in my starting the challenge is about to kill me but I have no alternative. However, come 12-10, the only way I won't start is if I'm not breathing anymore!!! Any help in this matter would be greatly appreciated. Thanks to everyone so very much for your help. I look forward to conversing as well as meeting many in the future.
