i havnt overdone myself at the gym as i told them i had anxiety so i do the pace im comfortable with. i warm up for 5 mins on a bike then go on the toning up equipment which isnt bad then i go on the cardio which is 20 minutes on the bikes and 20 minutes on the treadmill. iv seen some right show offs running on the treadmill for ages but i just stick to walking as i suffer anxiety. 1st time i went i came home and as soon as i sat down i fell asleep and it was only 4pm and 2nd time i went i became weak and shaky. i know theres something not right but i dont know wether its through the withdrawl, my nutrition or wether im dehydrating myself.
