Your program WORKS. I am over 50,and even though I have 3 marathon under my belt ( and finished them), I could not do 5 straight push ups, now I can do a set of 50. I went through AX1 twice,( out of my home using your replacements) it helped my running performance. The last 400 challenge I finished in 12 minutes down 28 minutes from the 40 minute mark I hit the first time. I am sure I will be going through AX2 soon and can not wait to see what is in store for me. Thank you and all the best.
