Had my son nearly 2 years ago. Haven't set foot in a gym for about 3 years. I'm very unfit, need to lose a bit of weight, so decided to join a gym and do some classes (which I used to love around 6/7 years ago!). I'm so nervous to go to the classes now, feel like everyone else will be looking at me because I'm so unfit. Really self conscious. Can anyone help me feel slightly less nervous?
