How to work out
There's no way around it - if you're going to unleash a new physique on Valentine's Day, then the next month is going to involve a ramped up exercise regime. But don't be scared, says Walsh: "Now that the diet is sorted, it's time to look at your fitness programme. Thankfully, there is no need for marathon sessions in the gym. Keep it short and sweet. The catch, however, is that you're going to be exercising more regularly, which means your home will also be your gym for the next few weeks.
"Use a mixture of cardio and resistance exercises for the best results. Imagining a scale of 1-10, aim to keep an intensity level of at least seven. Be honest with yourself; if you want quick results then you're going to have to up your game. Try this weekly programme which, alongside your improved diet, will make sure you face Valentine's Day in the fittest, healthiest, sexiest shape of your life."
