Hey guys,
Ive had a terrible month and need some advice on getting back on!
start of the month my long term girlfriend dumps me, so been on the drink for 2 weeks solid then got a chest infection for another 2 weeks and just now getting over it!
not been in the gym for a month and my diet has gone down the pan!!!
i cant believe how quickly my gains have gone down and how much bloody weight ive put around my gut so quick!!
any ideas of whats good to get back into into it? i was doing so well?
i cant wait to get back into the gym and get pumping, i miss it like mad!
cheers guys
