Muscle fitness is one of three important types of overall physical fitness. The others are aerobic fitness and flexibility.
When you increase your muscle fitness, you'll notice that you can carry heavy grocery bags more easily, pick up children without feeling as much strain, or carry heavy items longer before you get too tired to continue.
Benefits of muscle fitness include:
How do you get healthier muscles?
Muscles become stronger when they are used regularly, but especially when they have to work against something. This is called "resistance."
For example, you use your arm muscles when you bend your arm at the elbow. But when you do the same movement with something heavy in your hand, your arm muscles are working against more resistance.
"Resistance training" means using things like weights, rubber tubing, or certain exercises to make your muscles stronger. It's a 3-step process:
A resistance-training program to increase muscle fitness can include:
How can you strengthen your core?
One part of muscle fitness is strengthening the muscles of your trunk. This is called core stabilization.
Core stability benefits everyone, from older people to top professional athletes. It can help you have better posture and balance, and it can help protect you from injury.
How often should you do exercises to strengthen muscles?
Experts say it's best to do exercises to strengthen muscles at least 2 times each week.1 Examples include weight training or stair climbing on 2 or more days that are not in a row.
"Repetitions" and "sets" are terms used to describe how many times you do a specific exercise.
The number of repetitions and sets you do depends on your goals. If you want to gain strength, do a few sets of a few reps with heavy weights. But you may want muscular tone and endurance, which means a few sets of many repetitions with light or medium weights.
For best results, use a resistance (weight) that makes your muscles tired after 8 to 12 repetitions of each exercise. As you build muscle strength, you'll notice that you can do more and more of each exercise. Some people will see a change in the way their muscles look, but others will not see a change for a long while. A more important sign of progress is how many repetitions and sets of an exercise you can do, or how much easier it feels to do them. This means that your muscle fitness has improved.
How can you get started?
By starting slowly and using the right technique, you may find that weight training is an enjoyable and effective way to build strength.
