I put this up the other day on my experience training this summer with Warbird Academy. Because of my low back history and knowing that I don't respond well to heavy spinal loading, we've managed to still make incredible gains while intelligently training around these limitations.
My progress has been astounding. Training 5 days per week, I have regained just about all of my lower body strength in 4 weeks and added about 5 lbs of bodyweight. Check out the article to see the specific exercises we've been using and leave any questions you have!
