12 Important Benefits of Strength Training

Strength training, also called weightlifting or resistance training, does more than just build muscular strength, though getting stronger is certainly a major plus. And, the good news is that if you’re not a fan of the gym, you can also strength train at home, in a park or outside, or just about anywhere in between because you don’t actually need traditional weight machines or a squat rack loaded with every weight plate imaginable to get in a good strength training workout. In fact, any form of resistance works, from dumbbells to barbells, kettlebells to weight machines, and resistance bands to just your own bodyweight—the key is just to place your muscles under a load.

A good set of resistance bands, adjustable dumbbells, or even a TRX suspension trainer can be all you need at home to get in a challenging, total-body strengthening workout. If you’ve been counting yourself out of strength training workouts because the gym just isn’t your scene or you’ve been reluctant to venture over from the cardio equipment at your gym to the weights, keep reading for a list of the benefits of strength training, which may be just the inspiration you may need to diversify your workout routine and take your fitness to new levels.

Benefits of Strength Training

In addition to its versatility and convenience, strength training is an efficient and effective workout that provides a variety of physical and mental health benefits, including the following:

Strength Training Strengthens Muscles and Connective Tissues

The first one is straightforward: strength training makes your muscles, tendons, and ligaments stronger. By requiring your muscles to work against a load, they develop more strength, which can make everything easier, from running a marathon or sprinting down the court to sink a layup to carrying a bag of groceries up the stairs.

Strength Training Builds Lean Body Mass

Particularly if you are lifting for hypertrophy, which refers to increasing muscle size and involves lifting heavy weights or working under high loads, strength training can build lean body mass. Putting on muscle not only can look good and cause favorable shifts in your body composition, but it also improves markers of health, increases your metabolic rate, and make you stronger and fitter.

Strength Training Reduces Body Fat

Like all forms of exercise, strength training burns calories, but the main metabolic payoff is that by building lean muscle mass, strength training helps increase your metabolic rate. Because your muscle mass is the primary determinant of your metabolic rate, putting on more muscle helps you burn more calories in a day, even at rest. Because of these beneficial body composition changes, weight training is one of the best forms of exercise for those looking to reduce body fat. Studies have found that 8-12 week strength training programs are usually just as effective—if not more so—at reducing waist circumference and body fat percentage as long-duration cardio exercise workout routines.

Strength Training Increases Bone Density


Increasing your bone density is critical for the prevention of fractures, particularly as you age. Strength training loads the bones, which signals them to lay down a denser, more mineralized boney matrix. Furthermore, when stronger muscles contract, they pull more forcefully on the bones, which also signals your body to deposit more minerals and strengthen the structure of your bones and create new bone cells.

Strength Training Helps Prevent Injuries

Strength training reduces the risk of overuse injuries from other sports (running, cycling, tennis, swimming, basketball, etc.) as well as activities of daily living because it strengthens your muscles, tendons, joints, ligaments, and bones. Building muscular strength allows the muscles and tendons to absorb more of the forces involved when you land during each step, running stride, or jump, removing undue stress that your bones and cartilage absorb when otherwise weak muscles fatigue.

Strength Training Improves Neuromuscular Control

Some of the greatest initial gains in muscular strength after embarking on a strength training program are actually due to enhancements in the communication between the brain and the muscles via nervous impulses. Strength training helps your brain and muscles coordinate their activities, such that a greater number of muscle fibers are recruited with an impulse from the brain and they contract in a more coordinated fashion, which makes for more forceful contractions. This can translate to overall improvements in coordination and muscle control, whether taking on fine motor skills or large, gross movement patterns.

Strength Increases Core Strength

Particularly when you perform unilateral exercises, such as a single-arm farmer’s carry or a rear-elevated Bulgarian split squat with a lateral rotation, strength training can improve core strength. Your core muscles, which include the abs, obliques, glutes, hip muscles, and lower back muscles, connect the upper body and lower body muscles and are instrumental in movement efficiency.

Strength Training Boosts Athletic Performance, Speed, Power, Efficiency, and Economy

By increasing strength, power, force generation, coordination, core strength, and balance, strength training increases your overall athletic performance, movement efficiency, and fitness. Gains in the weight room can lead to faster running, higher jumping, better swinging and hitting, and further throwing.

Strength Training Can Improve Markers of Health

Studies have demonstrated the ability of strength training workout programs to improve numerous markers of health. For example, resistance training programs have been shown to lower blood pressure, improve blood sugar control, and decrease triglycerides and cholesterol.

Strength Training Can Optimize Hormonal Balance

Strength training can improve your hormonal balance by stimulating the production of hormones like testosterone and growth hormone and inhibiting stress hormones like cortisol, which when high, can contribute to weight gain.

Strength Training Can Boost Your Mood and Reduce Anxiety

All forms of exercise produce endorphins, the feel-good chemicals that can elevate your mood. It’s also a great way to relieve stress and anxiety, as it has been shown to reduce stress hormone levels.

Strength Training Can Increase Your Confidence

Let’s face it, when you feel good about your body, you walk around with confidence and a little more swagger. As you get stronger, you feel better about yourself and that can carry through into all areas of your life, from workouts to work to relationships.
