Muscle Strength vs. Muscle Endurance: Which Is Better?

There are two types of people who lift weights: those who want big muscles and those who just want to tone and tighten up without getting bigger. Those looking for size tend to grab the heaviest weights and stick to fewer reps. Those who are afraid of “bulking up” generally reach for the lighter weights and do more repetitions to achieve a “toned” look. So is this the right way to go? Is there a difference between these two types of training? 

Strength vs. Endurance

Learn the difference between muscle strength and muscle endurance.

Yes, there is a difference behind these two types of training, but everyone needs both types of training for a well-balanced muscular system and a high-functioning metabolism. These two types of strength training are about muscle strength vs. muscle endurance. Doing fewer repetitions with more weight will help you increase your strength. On the other hand, doing more repetitions with lighter weights will help you build endurance. You absolutely need both in your everyday life.

Muscle strength is the ability to exert a maximal amount of force for a short period of time. For example, lifting something very heavy. In the gym, that may be bench-pressing a heavy barbell for 5-8 repetitions. In your real life this may look more like moving a heavy piece of furniture or pushing your car out of a snow ditch—that requires strength.

Muscle Endurance, on the other hand, is the ability to do something over and over for an extended period of time without getting tired. In the gym, that may be doing 50 bodyweight squats in a row, moving to a rhythm. In your real life this might look more like using your legs to push a lawn mower for an hour, or carrying boxes back and forth when you are helping someone move.

How to Plan Your Strength Workouts

While at the gym, you will see a variety of people doing a variety of strength and endurance exercises. When teaching a strength class, I always incorporate some exercises that build muscle strength and some that involve muscle endurance to round out the participants’ training because as I said above, out in the real world, you never know whether you’ll need strength or endurance to complete everyday tasks.

Therefore, when you plan your own workouts, try to focus on both muscle strength and muscle endurance. Some days it will be good to focus on endurance and use lighter weights going for more repetitions. This is often combined with cardio exercises. However, it is crucial that you also spend at least two days a week using heavy weights so that after only a few repetitions you are at muscle failure. This not only keeps you strong, but boosts your metabolism to run at a higher rate. How you ask? More muscle on your body, more calories you will churn through every single day even at rest.

Lastly, I want to dispel the myth that using heavy weight will bulk you up. Men genetically can develop more muscle mass through heavy lifting. However, women, for the most part, do not have the type of testosterone to create that huge muscle bound look. And like I just said, more muscle is a good thing. The more muscle you have, the more calories your body will burn throughout the day and the more capable you will be to perform any activity that comes your way.

Where Do I Go From Here?

If you are looking for a lean, sculpted appearance the answer is simple, though perhaps not easy:

1. Strength train with heavy weights as least two days a week

2. Do at least 150 minutes of cardio exercise a week; that’s 30-minutes a day for most days to burn calories and reduce body fat. I suggest interval training that combines cardio activity with muscle endurance exercises. For example, bodyweight jump squats or jumping jacks or punches. 

3. Choose a healthy, clean diet including lots of lean protein and vegetables along with some fruits and complex carbohydrates. Limit your sugar and alcohol intake.
