Fitness Appraisal

I feel like I've gained a little weight while I've been sick so I've decided to take action immediately. I'm renewing my gym membership for a month (I've put aside the money already) & I've booked a fitness appraisal for tomorrow morning at 6am (it was the only time slot they had left >_<). I hereby commit to doing my new routine at least 3 times a week, my goal is to flatten my stomach, shape my butt & tone my thighs; also if I have gained any weight I intend to work it off asap.
