Stand with the feet slightly apart, a dumbbell in each hand and the arms relaxed, looking straight ahead:
• Inhale, slightly arch the back, and bend the knees.
• When the thighs reach horizontal, extend the legs to return to the initial position.
• Exhale at the end of the effort.
This exercise mainly works the quadriceps and the gluteal muscles.
Comment: There is no point in working with heavy weights. Working with moderate weights in sets of 10 to 15 repetitions provides the best results.
