Lunge with a MB Twist
This exercise is another combo working your quads, glutes, hamstrings and your obliques.
Engage your core, standing hip width apart with shoulders relaxed. Holding a medicine ball a few inches in front of the chest, step forward into a lunge with the right leg. (Safety first! Keep the knee from sliding forward past the toes.) Get deep into that lunge, making sure the front thigh is parallel with the floor, then with extended arms, reach the medicine ball to the right, rotating the torso at the same time. Maintain the lunge and return to center. Come to standing, then lunge with the other leg (and rotate to the left this time). Do the twist in place, or moving forward as walking lunges.
If you do this as a walking lunge, you will get a cardio effect with it and burn more calories.
