Mulling it over

The gym, where I work, is having a 'challenge' in the new year. An 8 or 12 week challenge ( not sure which at this stage) and I'm wondering if I might join in and give it a go. I don't seem to have very good staying power with these sort of things ( mostly the eating) so it might just assist me to keep on! It involves a personal training session and a 'weigh in' and advice and look at what's been happening in the eating department for the week.
