I'm currently 3 Months into gym membership. I now go nearly every other day and do a mix of all sorts - spin, PT with the staff, weights, les mills etc.
I'm feeling great but sometimes I feel like I hit a wall during a class or workout and feel very tired after.
I'm too scared to ask as everyone is wandering around with pink drinks, shakes after etc. I feel like a total novice.
Any basic rules I should be following?
