If you still prefer workouts later in the day, they can have their own unique benefits, too. Evening exercise — between 6:30 p.m. and 8:30 p.m. — “greatly” increased upper body muscle strength, power and endurance, and enhanced overall mood for women, according to the study published in Frontiers in Physiology.

For your heart health, ACSM guidelines recommend 150 minutes of moderate-intensity aerobic physical activity each week. In a given week, that works out to 30 minutes of moderate exercise five days per week. Or if you're looking to do more with less time, ramp up the dial.

The World Health Organization (WHO) recommends that adults engage in at least 150 minutes of moderate-intensity aerobic physical activity per week, or 75 minutes of vigorous-intensity aerobic physical activity per week. This can be broken down into smaller increments, such as 30 minutes a day for five days a week.

However, most experts agree that the maximum time you should exercise per week is about 10 hours. This includes both aerobic and anaerobic exercise, and it's important to mix both types of exercise to get the most benefit.
