I was in recovery from a dangerously active thyroid and my doctor said that I was on the verge of affecting my bone marrow. Struggling to get out of my own way &11 kg heavier, I decided that this is what I needed to get my fitness back. I lead a very busy working life so the short 20 mins early morning sessions are perfect for me. First one was a serious struggle, but after a few weeks I started to recover faster & sleeping better. I’m now, back to strength training at the gym and I’m on the road back to great health.
