Roll with it 

This workout was designed by physical therapist Mary Beth Knight for mums with babies up to the age of around nine months.

Side reach 

Stretches and strengthens the muscles on the sides of the stomach

Start with right hip facing (and a few inches behind) the buggy, right hand on the handle. Reach your left hand overhead and bend your upper body to the right, gently pushing the buggy away from you as you go. Reverse direction, bringing your upper body back to starting position and pulling the buggy back in. Repeat with left hip facing the buggy. Do 15 repetitions on each side.

Pendulum legs 

Lower body warm-up and cardio

Stand behind the buggy with your hands resting lightly on the handle. Raise one leg out to the side, keeping the leg straight but the knee soft, not locked. Lower the leg slowly back to the starting position. Alternate legs for one minute. You can do this move standing still or walking forward.

Torso twist 

Total body warm-up and cardio

As you jump a few inches off the ground, twist at the waist so your upper body turns in one direction and your lower body in the other. Keep your knees soft as you land. Repeat for one minute. Singing Twist and Shout" is optional but can help keep your baby entertained."

Bicep curl 

Strengthen arms

Stand with feet about shoulder-width apart, grasping a full water bottle of equal size in each hand. With arms at your sides, palms facing forward, bend elbows and slowly lift the bottles almost to your shoulders, keeping wrists straight and the rest of your body still (no rocking to help you lift). Do a set of 12.

Rocking lunge 

Strengthens lower body

Stand behind the buggy and take a big step back with one foot, keeping both feet pointing forward. With a bend in the back leg and your weight on the heel of the front foot, sink down until your front knee is bent 90 degrees, pushing the buggy forwards as you sink. Don't let your front knee extend past your toes. Pull the buggy back as you return to standing, gently rocking your baby. Do 12 times with each leg.
