Think of how hard it is to get fit again after countless months of over-indulging. Every year it’s the same thing. January comes around and we tell ourselves that, this time, it’s going to be different. This time we’re committed! So, instead of gradually easing into a sensible fitness routine, we hit the gym hard for a week or two, pumping those weights and treadmilling as if our lives depend on it. Then it all fizzles out. We’ve tried to do too much too quickly. We lose motivation. And we’re back to square one again.
