Day 1: Perform 30 minutes of rowing, 25 side crunches, and 15 upward-facing hip flexes. Start with cardio to get your heart pumping before moving to muscle-toning exercises.
Day 2: Perform 30 minutes on the elliptical, and alternate 10 minutes of the corkscrew Pilates move with 10 minutes of the jackknife Pilates move. Pilates routines force you to focus on muscle control and slow, deliberate movements that build strong, lean muscle.
Day 3: Perform 30 minutes of running, and follow with 40 exercise ball reverse crunches and 40 leg lifts. These abdominal exercises will work your core and your lower abs as well as your lower back. Alternate exercises in groups of 10 without stopping until all 40 repetitions are complete.
Day 4: Perform 30 minutes on a stationary bike, and then 2 sets of 12 scissor twists with an exercise ball, and finish with 3 sets of 15 sit-ups. If you feel physically able to perform additional sit-ups, place your hands behind your head and bring each elbow to the opposite knee with each sit-up to work side abdominal muscles in addition to your central abs, and perform another 1 to 2 sets of 15 sit-ups like these.
Day 5: Run 30 minutes on a treadmill and then follow that with 20 Pilates boomerang moves, and 3 minutes of Pilates “hundred” moves.
Days 6 and 7: Rest your body. Take 1 to 2 days of rest each week from cardio routines and 2 days of rest from exercises that target your abdominal muscles, preferably spacing your rest days throughout the week to give your muscles time to recover and repair themselves.
