Doing a low impact circuit workout can be a great way to get your heart rate up without strenuous exercises. Intermountain Healthcare Heart Institute exercise specialist Jeffrey Beck says to complete each exercise in succession without rest in between. Once you have gone through all three exercises, rest for one minute and repeat as many times as you want.
1) Side Step: Place your feet shoulder width apart and come down into a quarter squat. Step your right foot out to the side and then back to the starting position. Do this as quickly as you can for 30 seconds and then switch sides.
2) Low Box Steps: Place your feet shoulder width apart and come down into a quarter or half squat position. Step forward with your right leg followed by your left. Return to the starting position by stepping back with your right leg followed by your left. Do this continuously for one minute.
3) Oblique Crunches: Place your feet shoulder width apart. Raise your left knee up to the side as you bring your left elbow down to meet it. Do this for 30 seconds and then switch sides.
