I tried the product Red Blast last night from The AF Store. Let me tell you, it did it's job. I never dread going to the gym but last night I had a grueling workout ahead of me. It was my dynamic effort squat/deadlift night and I hit 2 pr's!! So Red Blast help me turn my night around. My lower back did not get as tight as it did last week for some reason(that's a good thing). My strength, focus and energy were all improved. So, if you're having a little trouble getting fired up to go train you should give this product a try. For details on my pr's go check out my training log.
