According to fitness expert Sarah Robichaud, building muscle is a great way to lose weight, stay youthful and live well. The key is a well-rounded routine that targets the five muscle groups: legs, abs, chest, back and arms. But guess what? You can work 'em all at home with no special equipment! Here's how:

1. Legs

Muscles: quadriceps, hamstrings and gluteus maximus

2. Abs

Muscles: rectus abdominis, transverse abdominis and obliques

3. Chest

Muscles: pectoralis major

4. Back

Muscles: trapezius, deltoids, latissimi dorsi and erector spinae

5. Arms

Muscles: triceps brachii and biceps brachii
