How do I get started?

  • If you have health issues – talk to your doctor and ask to see a physical therapist

  • Choose an activity that you enjoy. It can be as easy as walking or gardening or as intense as hiking or running

  • Find a friend! Having the support of a friend of family member will help keep you going

How much should I do?

  • For most healthy individuals: 30 minutes, 5 days a week of moderate intensity aerobic exercise OR 20 minutes of high intensity aerobic exercise

  • A quick way to gauge intensity is Target Heart Rate. To calculate: 220 – (your age) x 70%. Example: 220 – 45 years old x .70 = 122.5 beats per minute (bpm)

  • You should be able to carry on a conversation with your walking partner without shortness of breath

Can I over-do it?

  • Absolutely! Just like a sedentary lifestyle, overactivity can have its own negative consequences like injury and reduced immune function

  • Developing a consistent exercise routine is key in preventing over-training, this includes rest days

  • A workout or training session is only as effective as how much you can recover from it

What’s considered “in-shape”?

  • Everyone will have their own unique definition of fitness, related to their fitness goal

  • A lower resting heart rate is just one indicator of fitness, normal RHR is 60-100 bpm
