Countdown (Choose Option 1 or 2)
Alternate between the two exercises without resting. For your first round, do 10 repetitions of each exercise. For your second round, do 9 reps. Then do 8 reps for your third round, and so on. Go as low as you can, or until you reach zero. Each week, raise your starting rep count by 1—so if you did reach zero, you'll start with 11 repetitions for the second week.
Option 11. Single-Arm Dumbbell Swing:
Using an overhand grip, hold a dumbbell at arm's length in front of your waist. Bend at your hips and knees and lower your torso until it's at a 45-degree angle to the floor. Swing the dumbbell between your legs, and then thrust your hips forward and swing the dumbbell up to chest level as you stand. Reverse the move, and repeat.
2. Squat Thrust: Stand with your feet shoulder-width apart and your arms at your sides. Push your hips back, bend your knees, and lower your body as deep as you can into a squat. Now kick your legs backward so that you're in a pushup position. Then quickly bring your legs back to a squat. Stand up quickly and repeat the entire move.

2. Explosive Push-Up:
Assume a pushup position, your hands slightly beyond shoulder width. Your body should form a straight line from your ankles to your head. Bend your elbows and lower your body until your chest nearly touches the floor. Press yourself up with enough force that your hands leave the floor.
