Is it safe for me to exercise?
You may feel uncertain about starting to exercise. The first step is to talk to your health care provider to find out if it is safe for you to exercise, what type of exercise or program is best for you and how much.
Your doctor may order a cardiopulmonary exercise test to determine a safe level of exercise for you.
How should I start exercising?
Starting to exercise for the first time or resuming exercise after a long break can be hard at first. It is best to start slowly, go step-by-step, and take breaks whenever you need them. Also, it is important to monitor how you feel during exercise.
Tips to start a regular exercise routine:
- Plan to start exercising two to three days each week. Slowly work your way up to an end goal of exercising five days each week.
- Start by exercising for 10-15 minutes at a time. Slowly build up the time you are exercising. Your end goal should be to exercise for 30 minutes.
- Always make sure that you begin and end your exercise with a five minute ‘warm-up’ and ‘cool-down.’ Perform stretching exercises after your “cool down” is complete. This will help to reduce the stress on your heart and muscles and prevent injury.
- Make an exercise schedule for each week and try and stick to it.
- Use a diary or journal to track your exercise routine and how you are feeling during exercise.
- Use a self-monitoring tool, such as the Borg Rating of Perceived Exertion (RPE) Scale, to help measure how you feel during exercise. The Borg RPE is a numerical scale that you can use to monitor how hard you are working during exercise. The goal is to be between three and five on the scale.
Moderate intensity aerobic exercise is best for the cardiovascular system. You can try:
- Brisk walking
- Cycling (either outdoor or on a stationary bike)
- Water aerobics
- Fitness classes such as Zumba
Strength or Resistance Training
- Use light free weights (no more than 5-10 lbs.) or resistance bands
- Do short sessions of 10-20 repetitions with the light free weights, two to three times per week.
Cardiac rehab will provide you with an ‘exercise prescription’ that is tailored to your health needs. While in cardiac rehab, you will be supervised during exercise. You will receive training on how to exercise safely, monitor your symptoms during exercise, and reach your individual exercise goals. For those people who cannot attend on-site, home-based programs are also offered which include ongoing contact with exercise specialists.
Cardiac rehab also provides education and support on how to manage risk factors for heart disease, such as eating a healthy diet and losing weight.
