To maintain a healthy physique, on average, most people should work out at least three times per week. When trying to reach a fitness goal or lose weight, it may be necessary to work out five to six days each week.
The type of workouts often factor into the number of days a person needs to exercise each week. For example, fat loss programs may require cardio three days each week and weight lifting or strength training two days each week. Alternating the type of exercise may enhance the overall results. When weight lifting, people may focus on lifts to target the chest one day, legs another day and shoulders and arms on the third day.
