Just for the record i am approaching 50 a....ya dont realise when your in your prime you should enjoy those years (pain free movement) coz when you get older everything hurts ha ha thanks again will post how im getting on in a few weeks.
Dude that made me laugh, not at you but with you. Nodding my head as I type this. Mate for me I would give plenty to still be in my 40's, late 40's or not. Wait till you get to wave goodbye to your 60h birthday my friend and then see how hard it gets staying in shape.
Hearing about the shoulder injury just reinforces what I said about getting hold of a personal trainer that has at least a level 3 qualification and or is a physio or kinesiologist. You will be able to train again, what will change is your range of motion and what kinds of things you can do.
Keep us in the loop how it goes please.
