Use the stroller for support as you walk and lower down to 90 degrees with your knees.
Squat down, pressing your hips back and keeping your chest upright.
I love to play peek-a-boo while doing calf raises behind the stroller! Slowly raise up and down on your toes.
Do 20 reps on each side with this one! Keep your upper body straight and raise your heel at a diagonal to your body.
Lift your knee up to the side, squeezing your obliques with each rep. Standing abs are a great way to ease into core work.
My kids think this sumo squats are funny! Point your toes and knees out, and lower your body straight down.
Always check with your doc before starting a new exercise program, and have fun with your workouts!
