I just wanted to provide an update to those who responded to my 5k warmup question a while back.

Through the use of training with B3 bands I was able to shave almost 3 minutes off my personal record for a 5k race in just a few weeks. What makes it even more impressive is the fact that I am not running very much at all. I am currently dealing with two herniated discs in my low back so I run no more than 5 miles per week maximum due to the back pain. I run 2 separate miles with bands on each week. My current cardio routine is mainly treadmill rucking, some stairs, sporadic speed ladder drills and assault bike (all with bands on). My mind is completely blown that I was able to drop my 5k PR from 26:08 to 23:15 with minimal running. I use the bands every single day for strength training and always have some sort of banded cardio warm up prior. My easy pace training training runs are now faster than what my maximum effort race pace used to be. Amazing results just keep coming!
