Getting back on the wagon

In the past few months I've fallen off the wagon, I have managed not to put on any weight but I've lost only 1kg in about 2 months, I feel tired again and can't be bothered most days, I haven't hit the gym in about a month and it's time I get up dust myself off and start again.

I lost my gym buddy earlier this month (she's ok don't worry, but due to unforeseen circumstances she's had to leave the gym) and I think since then I have been lacking the motivation to go alone. 

But today I took the first step, I signed up for a 6week challenge at my gym, so I have goals and a program to keep me responsible for my own success, so I stated day 1 of better me 2.0 with a body sculpt class, and I hurt already, but hopefully I can keep at it and feel as happy and confident that I did only a few short months ago
