Weight training offers many benefits. It helps you build muscle, relieve stress, and keep your mind and body healthy. If you’re dedicated enough to your nutrition, you could even sport the fabled six-pack on the beach this summer. However, being aware of both the advantages and disadvantages of weight training is key to staying healthy and getting in better shape.
Weight training is a workout using weights as resistance to strengthen your muscles and improve their tone. It may enhance your balance and flexibility, allowing you to live more independently as you age. This activity may also reduce blood pressure, blood sugar and cholesterol levels, increase bone density, accelerate metabolism and contribute to brain health.
Recent research also suggests that weight training can improve cardiovascular health and support joint longevity when done correctly. Just 30 minutes of strength-building exercises per week can lower your chances of premature death due to heart disease.

If you experience chronic pain, live with a heart condition and struggle with weight management, this training may be beneficial. Aside from aiding physical health, this workout may also help you be more mentally fit. Weight training may alleviate symptoms of depression, boost your self-confidence and sharpen your cognitive skills — like thinking and learning.
This workout generally involves free weights, including:
You can also do various exercises with weight machines. Examples include:
The suitable exercise and equipment depend on your health goals, fitness level and experience. Regardless of what you aim for, how fit you are and how many times you’ve done weight training before, you should observe some of these best practices to notice gains more quickly and protect yourself:

Weight training offers numerous advantages, including building muscle, relieving stress, and supporting overall mental and physical health. However, it’s equally important to understand the disadvantages of weight training, so you can train safely and effectively. Although there are not many disadvantages to going to the gym, new gym-goers may experience some form of injury within the first few months of training. This highlights the need for caution.
As with any other physical activity, proper techniques and planning are essential to obtaining the desired results. Otherwise, things could go terribly awry — it’s rare, but it happens. Here’s what you should know about the disadvantages of strength training, and other forms of weight training for that matter, and ways to minimize the risks.
Hitting the gym isn’t inherently dangerous, but the injury statistics bear a grim warning. A study of 4,785 male and 542 female members of a U.S. Army Division revealed that 4.5% of men and 0.6% of women got hurt throughout one year of weight training. These figures translate to 0.31 and 0.05 injury incidents per 1,000 hours between the two genders. What lurks behind these fitness foibles?
The most significant disadvantage of weight training is that anyone can do it. The gym’s accessibility should be a huge benefit, but people vary widely in their fitness expertise and don’t always get their information from reliable sources. Beginners usually don’t realize their mistakes until too late, resulting in a sudden and often severe injury. This vicious cycle is one of the main cons of weightlifting that turns skeptics away.
Far too many gym-goers use improper or even dangerous techniques they see online or witness other people doing. Improper form in exercises like deadlifts or bench presses accounts for many gym injuries. For example, it’s not uncommon for folks doing Romanian deadlifts to strain their lower back and cause chronic back pain.
Back strains are statistically the most common weight-training injuries, but there are many others. Shoulders, knees and elbows are also injury-prone areas because of the pressure they have to endure. These disadvantages of lifting heavy weights often scare people away from specific exercises.

What’s your best bet for avoiding injury? Hire a personal trainer — even if only for a session or two. You might even get this service for free. Many fitness facilities help new members learn proper weight-lifting techniques as part of the package. Please take advantage of this benefit if offered.
You might also consider sticking with strength training machines instead of heading to the free weights — especially if you’re a novice. The fixed nature of these devices reduces your injury risk by operating in a fixed range of motion to guide weights up and down. You won’t work as many complementary and opposing muscle groups, but you’ll prevent unnecessary strain.
Another pro-tip: go light. Far too many injuries occur when people bite off more than they can chew — a classic example involves getting pinned under a bench press bar. It also helps to have a spotter, even if they aren’t a professional trainer. They can help you with those heavy lifts and critique your form. Plus, working out with a buddy motivates you to stick with the program.
Most people understand the “weekend warrior” syndrome — you remain relatively sedentary all week, then hit the gym hard on the weekends. Come Monday, you hobble back into the office with every part of your body screaming.
Overtraining — which happens to be one of the disadvantages of powerlifting — is a significant risk of weight training. It can occur when you work out at an intensity level that is too high for too long without a break while ignoring the subtle signs that you should slow down. Ironically, training too hard or too frequently can derail your progress because it can result in injuries or performance plateaus.
Overtraining can also lead to elevated cortisol levels, disrupted sleep patterns and immune system suppression, thereby increasing the risk of illness and injury.
How can you recognize when you’ve pushed past your limits? Look for the following signs:
There is a common misconception among fitness beginners that you need to train two or three hours a day. This idea could not be further from the truth. To avoid the disadvantages of resistance training, limit most sessions to one hour to maximize the benefits. After one hour, the benefits plateau. After two hours, you’re doing more harm than good. You may even be able to get a good pump in with an at-home workout that lasts around 45 minutes.
Overtraining not only slows progress but may also lead to quitting your fitness program altogether. You must train in moderation for the good of your physical and mental state. Gradually elevating your exercise routine may help you sustain the habit longer rather than burning out or experiencing an injury.

Here you can see a powerlifter wearing a belt and knee wraps while performing a heavy squat. These accessories are absolute must-haves if you want to reach maximum strength levels with minimum injury risk.
Lifting something heavy can result in joint strains and sprains, which is ironic because exercising can ease your pain if you have arthritis. It builds the muscle around your joints so your cartilage doesn’t have to do all the work. Whether you benefit from healthier joints depends on your form and the resistance level you select.
You can avoid or minimize joint pain by following these tips:
Some low-impact workouts like swimming, walking or golf are gentler on your joints and will help you work out without getting injured. Moreover, you may feel joint pain due to improper diet. You should eat anti-inflammatory foods, such as beans, berries, fish and green tea. You could also take a collagen protein supplement to improve skin and joint elasticity.
Everyone’s flexibility range differs. You could find yourself limited compared to your previous stretching ability. Although you can gradually improve your flexibility with specific activities, your genes, age, height and injury history may limit your range of movement.
Fortunately, you can easily address this concern. You will see noticeable benefits to your tight muscles by performing some post-workout flexibility exercises. Incorporating post-workout yoga and stretching can mitigate tightness, improving performance and reducing weight lifting side effects. You can do this simple routine at the gym or at home with some resistance bands whenever you can.
Additionally, you should devote your rest day to yoga practice to balance strength with elasticity. Strength training can still be the foundation of your exercise routine, but mixing in other workout styles is always a good idea so you don’t have any significant weaknesses.

If the thought of tearing open a major blood vessel inside your body scares you, it should. Arterial tears are probably the scariest disadvantage of lifting heavy weights. Although women mainly deal with spontaneous coronary artery dissection, men may sustain it after carrying a heavy object or doing strength training. Occasionally, other blood vessels — like the celiac artery — may also incur damage.
If you want to avoid rupturing a blood vessel at all costs but don’t want to give up strength training, avoid the heaviest exercises — like the bench press, deadlift or squat. Most arterial tears occur in a powerlifting setting when performing these three compound movements. Stick to machines, cables and lighter free weights.

Aside from the main disadvantages of weight training, there are several other factors to keep in mind if you want to achieve long-term success:
Recognizing these factors early helps you develop a sustainable fitness routine and prevents burnout.

While weight training is advantageous for health in general, these groups of people can find it more beneficial:
Any individual whose occupation involves backbreaking tasks needs to work on their strength. Firefighters, construction helpers, farmers, ranchers, warehouse workers, auto mechanics and the like are susceptible to musculoskeletal disorders, causing them to have bad knees, achy hip joints and lower limb discomfort.
Lifting heavy objects when you’re physically unprepared makes you prone to chronic pain and limitations in dexterity and mobility. These health problems may linger after you retire, so you should pursue weight training to condition your body and reduce your risk of injury.
While strength isn’t the primary determinant of success in some sports, this quality can take athletic performance to the next level.
For instance, height and skill are more vital to success in basketball than strength. However, players who lift weights can improve their durability, explosiveness, endurance, and stamina.
A good example is Giannis Antetokounmpo’s body transformation. He started as a lanky 6-foot and 8-and-a-half-inch forward and became a muscular near-7-foot MVP after pumping iron in the summer who’s unstoppable in the paint.
Stephen Curry is another living proof of what you can gain in weight training. Although he’ll forever be known as the greatest shooter in NBA history who ushered in the current era of the league, he’s an underrated scorer under the basket. His game also involves nonstop motion to free himself from pesky defenders. Curry’s strong legs allow him to remain active until he gets to his spots without getting tired quickly.
Being comfortable with resistance comes with the territory if you dream of being Mr. Olympia. Rigorous weight training is crucial to achieving a healthy balance of size, definition, and symmetry. Although genetics plays a significant role in developing the winning physique, unwavering dedication to weight training is the X factor.
Muscularity isn’t a requirement to win an Oscar or Golden Globe. However, many roles demand certain levels of muscle definition, aiding the audience’s suspension of disbelief.
Many actors exercise and diet to look good in public. Some are so dedicated to their craft they take weight training to the extremes, shocking viewers with mind-blowing physical transformations.
Christian Bale is one of the first celebrities to come to mind. A year after portraying a scraggy insomniac in The Machinist, Bale got bigger to fit the Batman suit for the first installment of Christopher Nolan’s The Dark Knight trilogy.
Those with a scrawny physique can benefit from weight training to improve their health and raise their attractiveness.
Setting foot into a gym with a slim frame can be intimidating. However, you can muscle up quickly when you concentrate on compound movements, eat at least 300 more calories than you should based on your current height and weight and take a break from training a few days weekly.
As you age, you naturally lose muscle mass. The more volume you lose, the more it can affect your motor function and negatively impact your quality of life. Weight training can help you keep or regain what you naturally lose as you get older, helping you move well for your age. Even two to three sessions per week can improve muscle strength, bone density and overall health for older populations.
Strength training is one of the best physical activities you can do. It tones your body while benefiting your mental health. It can even help you meet friends and make meaningful business connections in the gym.
However, you have to recognize the risks. Now that you know the disadvantages of weight training, you can take adequate measures to make your next sweat session safer and more productive.
