thank you so much for your opinion..for right now i dont even know whats a p90x..but i have noted that down for future...thanks for the prices..i wont be able to go to gym on sundays 'cause of the timings...so im committing to go mon to sat...first i wanna reduce my belly...and then get in shape overall...'cause even my chest aren't so flat...and then build some muscles...so i think at the beginning i will do some cardios and weight lifting with a day alertnation...thank you!
