Have any of you or someone you know done one of these? Are they worth it? After spending most of 2018 sick, culminating in a hospital stay for a burst appendix that I basically ignored for several weeks, and several bouts of light duty in between, I've been cleared and working full duty for about 2 weeks now. However, 1 foot pursuit and several fights has made it very obvious how out of shape I've gotten. My doctor told I'm good to do whatever as long as I don't develop any abdominal pains beyond some cramping or like a side stitch some people get when running. So far I've started easy, a few runs, basic calisthenic exercises, etc. I was wondering if the HTK Tactical Bodyweight plan in particular would be worth the money( since its around $24 right now) to help jumpstart my body to speed up the process of getting back where I need to be.
