How Hard Should Your Workouts Be?
There are a number of ways to determine whether you're working out at an intensity level that's good for you.
You can check your heart rate or you can assess your exercise intensity on a scale of 1 to 10. This method (rate of perceived exertion-RPE) helps to evaluate your activity level continuously throughout your workout, using a scale:
- 1-2: weak exertion
- 3: moderate
- 4-6: increasingly strong
- 7-9: very strong, vigorous
- 10: maximal; extremely strong
