## What is the general guideline for frequency of cardiovascular exercise?

When it comes to cardio: As a general rule of thumb, aim for a minimum of three cardio sessions per week. If you’re looking to lose weight, you might increase this number to five to six sessions. When it comes to strength training: It’s recommended to do some sort of strength training three to four times per week.

What is the heart rate reserve?

Determine your heart rate reserve (HRR): Your heart rate reserve is your maximum heart rate minus your resting heart rate. So, if you are 40 years old, your maximum rate is 180. Next, subtract your resting rate (we’ll say 80 in this example) and your HRR is 100 beats per minute.

What is the Karvonen heart rate formula?

The Karvonen formula is your heart rate reserve multiplied by the percentage of intensity plus your resting heart rate. For example, a 50-year-old with a resting heart rate of 65 would calculate as follows: 220 – 50 = 170 for HRmax. 170 – 65 = 105 for RHR.
