Welcome to our Flat-Belly Challenge : 21 days of workouts, belly-blasting tips, and fat-burning recipe ideas to help you feel slimmer and more confident all Summer. Day 5's challenge is to let your body relax and recover from all the hard work you've done this week!
Go ahead and pat yourself on the back! You've completed four days of intense workouts that have kept your heart rate up and muscles burning. Today it's time to pull back a bit and allow your body the rest it needs to recharge itself for tomorrow's workout. As any trainer will tell you, a rest day is just as important as a workout.
Before you hunker down on the couch, keep in mind that a day of rest doesn't always have to equal inactivity. Opt for some light cardio like a walk around the neighborhood, which will help get the blood flowing to tired muscles. If that doesn't appeal to you, give your body the stretch it needs by flowing through our restorative yoga sequence , and if all else fails, pull out your foam roller  to use in front of the TV.
And because it's Friday, the day wouldn't be right without a delicious cocktail to ring in the weekend!

Our pineapple mojito  can be made sans alcohol, but regardless of whether you leave the rum in or out, the cold-pressed juice contains pineapple and mint, which are both known for their detoxing and debloating benefits.
Bonus tip: If spending time poolside is part of your plan this weekend, take a cue from Cameron Diaz 's trainer on all the foods to cut out  to help you feel your leanest self. And not too worry! You still get to enjoy a bounty of whole foods, like fresh fruits and vegetables, lean protein sources, unrefined carbs, nuts and seeds, and healthy fats.
