The healthiest and most efficient way to firm up flabby areas of the body is through nutrition and exercise. To tone up without losing weight, it's important to eat the right foods and focus on a weight-training program. Eating foods high in protein and lifting weights three times a week will lead to a tighter body without any loss of weight. Muscle weighs more than fat, so focusing on muscle growth will not only make your body look and feel tighter but also will help you maintain your current weight.
Change your diet. You must focus on eating high-protein foods that are low in calories and saturated fat. Eat a protein, a vegetable and a fruit for every meal possible. Try to eat every few hours to help keep your metabolism high and your muscles fed properly.
Begin a weight-training routine. Use a high-quality weight bench set, dumbbells and an exercise ball (for working the core of the body). Start with light weights to avoid injury. Each workout should last 30 to 45 minutes, and you should do three sets of each exercise. The ideal number of repetitions is 12 to 15 per set; use enough weight so that you can do no more than this number of reps.
Work out three times a week with a rest day between each workout. Muscles need time to heal after being broken down during a resistance workout. Focus on two or three muscle groups per workout. For example, Day 1 could involve chest and back muscles; Day 2 could be devoted to legs and abdominal muscles; and Day 3 could focus on arms and shoulders.
Consume a whey or soy protein shake immediately after each workout. Ideally, you should take in about 50 grams of protein after a workout. Drink a protein shake each morning in addition to the post-workout shakes.
Follow this diet and exercise program for at least four to six weeks, and the results will be noticeable. You will have a much more toned body, and your body weight will be about the same as when you started the new routine.
