I recently been put on TRT, i have been injured for almost 10 years, getting a lot better thanks to prolotherapy and finally finding a competent chiropractor who studied physio and knows the whole ligament and tendon anatomy.
I am very pleased of my progress since i started training again with weights around October, i went from a terrible bench press last year of 100 pounds and sweating to my near max 220 pounds De***ber of this year.
At 39 years old i decided to change my way of training to avoid getting injured also i live in Canada and my first snow plowing was horrible, i was not even able to lift 2 shovels without being pooped out.
I decided to change my diet, lose the weight i gained since starting TRT, my medical doctor did not give me an AI and i gained a lot of fat and water due to this.
I decided to start P90X and see how everything goes, this morning i did chest and back, i was able to keep up with the warm up and do the whole thing, i was drained but it felt just good.
I kind of feel that P90X is the total body system for anyone wanting to get back in shape and ideal for the 40 year old.
