After puberty, the male hormone testosterone helps build muscle in response to weight training. Boys have more testosterone than girls do, so they get bigger muscles.

The focus of each training session should be on proper form and technique, with qualified instruction and supervision. Strength training is one part of a total fitness program.

Kids and teens should get at least 1 hour a day of moderate to vigorous physical activity every day, including aerobic cardio activity, like running, biking, and playing outside. Also, be sure you child drinks plenty of liquids and eats a healthy diet for better performance and recovery.

What Is Strength Training? What Are the Benefits of Strength Training? With a well-designed and supervised program, they can: improve overall fitness and sports performance increase lean body mass more muscle, less fat burn more calories make bones stronger improve mental health Who Can Do Strength Training?

Is Strength Training Safe? What's a Healthy Routine? Strength Training Program Guidelines Here are some guidelines when considering strength-training programs: Choose programs with appropriate instructor-to-child ratios. Some training programs may alternate splits weekly.

Exercise selection depends on the goals of the strength training program. If a specific sport or activity is targeted, the focus will be on specific muscle groups used in that sport. Various exercises may target improvements in strength, speed, agility, or endurance.

For strength and power training in able-bodied individuals, the NCSA recommends emphasizing integrated or compound movements multi-joint exercises , such as with free weights, over exercises isolating a muscle single-joint exercises , such as with machines.

Some studies have analyzed the differing muscle activation patterns, which can aid in exercise selection. Commonly used equipment for resistance training include free weights—including dumbbells , barbells , and kettlebells — weight machines , and resistance bands.

Resistance can also be generated by inertia in flywheel training instead of by gravity from weights, facilitating variable resistance throughout the range of motion and eccentric overload. Some bodyweight exercises do not require any equipment, and others may be performed with equipment such as suspension trainers or pull-up bars.

Strength training exercise is primarily anaerobic. Other goals such as rehabilitation, weight loss, body shaping, and bodybuilding often use lower weights, adding aerobic character to the exercise. Except in the extremes, a muscle will fire fibres of both the aerobic or anaerobic types on any given exercise, in varying ratio depending on the load on the intensity of the contraction.

At higher loads, the muscle will recruit all muscle fibres possible, both anaerobic "fast-twitch" and aerobic "slow-twitch" , to generate the most force. However, at maximum load, the anaerobic processes contract so forcefully that the aerobic fibers are completely shut out, and all work is done by the anaerobic processes.

Because the anaerobic muscle fibre uses its fuel faster than the blood and intracellular restorative cycles can resupply it, the maximum number of repetitions is limited. Circuit weight training is a form of exercise that uses a number of weight training exercise sets separated by short intervals.

The cardiovascular effort to recover from each set serves a function similar to an aerobic exercise, but this is not the same as saying that a weight training set is itself an aerobic process.

Strength training is typically associated with the production of lactate, which is a limiting factor of exercise performance. Regular endurance exercise leads to adaptations in skeletal muscle which can prevent lactate levels from rising during strength training.

This is mediated via activation of PGC-1alpha which alter the LDH lactate dehydrogenase isoenzyme complex composition and decreases the activity of the lactate generating enzyme LDHA, while increasing the activity of the lactate metabolizing enzyme LDHB. Supplementation of protein in the diet of healthy adults increases the size and strength of muscles during prolonged resistance exercise training RET ; protein intakes of greater than 1.

It is not known how much carbohydrate is necessary to maximize muscle hypertrophy. Strength adaptations may not be hindered by a low-carbohydrate diet. A light, balanced meal prior to the workout usually one to two hours beforehand ensures that adequate energy and amino acids are available for the intense bout of exercise.

The type of nutrients consumed affects the response of the body, and nutrient timing whereby protein and carbohydrates are consumed prior to and after workout has a beneficial impact on muscle growth.

A protein shake is often consumed immediately [53] following the workout. However, the anabolic window is not particularly narrow and protein can also be consumed before or hours after the exercise with similar effects.

If consuming recovery drink after a workout, to maximize muscle protein anabolism, it is suggested that the recovery drink contain glucose dextrose , protein usually whey hydrolysate containing mainly dipeptides and tripeptides, and leucine.

Some weight trainers also take ergogenic aids such as creatine [56] or anabolic steroids to aid muscle growth. As with other sports, weight trainers should avoid dehydration throughout the workout by drinking sufficient water.

This is particularly true in hot environments, or for those older than Some athletic trainers advise athletes to drink about 7 imperial fluid ounces mL every 15 minutes while exercising, and about 80 imperial fluid ounces 2. However, a much more accurate determination of how much fluid is necessary can be made by performing appropriate weight measurements before and after a typical exercise session, to determine how much fluid is lost during the workout.

The greatest source of fluid loss during exercise is through perspiration, but as long as fluid intake is roughly equivalent to the rate of perspiration, hydration levels will be maintained. Under most circumstances, sports drinks do not offer a physiological benefit over water during weight training.

Insufficient hydration may cause lethargy, soreness or muscle cramps. The effects of strength training include greater muscular strength, improved muscle tone and appearance, increased endurance, cardiovascular health, and enhanced bone density.

Strength training also provides functional benefits. Stronger muscles improve posture , [ vague ] provide better support for joints , [ vague ] and reduce the risk of injury from everyday activities. Progressive resistance training may improve function, quality of life and reduce pain in people at risk of fracture, with rare adverse effects.

Strength training causes endocrine responses that could have positive effects. body fat distribution is one predictor of insulin resistance and related complications.

Strength training also leads to various beneficial neurobiological effects — likely including functional brain changes, lower white matter atrophy, [80] neuroplasticity [81] including some degree of BDNF expression , [82] and white matter-related structural and functional changes in neuroanatomy.

Moreover, it also promotes decreases in total cholesterol TC , triglycerides TG , low-density lipoprotein LDL , and C-reactive protein CRP as well as increases in high-density lipoprotein HDL and adiponectin concentrations.

Stronger muscles improve performance in a variety of sports. Sport-specific training routines are used by many competitors. These often specify that the speed of muscle contraction during weight training should be the same as that of the particular sport.

The genealogy of lifting can be traced back to the beginning of recorded history [88] where humanity's fascination with physical abilities can be found among numerous ancient writings. In many prehistoric tribes, they would have a big rock they would try to lift, and the first one to lift it would inscribe their name into the stone.

Such rocks have been found in Greek and Scottish castles. Another Greek, the physician Galen , described strength training exercises using the halteres an early form of dumbbell in the 2nd century.

Ancient Greek sculptures also depict lifting feats. The weights were generally stones, but later gave way to dumbbells. The dumbbell was joined by the barbell in the later half of the 19th century. Early barbells had hollow globes that could be filled with sand or lead shot , but by the end of the century these were replaced by the plate-loading barbell commonly used today.

Weightlifting was first introduced in the Olympics in the Athens Olympic Games as a part of track and field, and was officially recognized as its own event in The s saw the gradual introduction of exercise machines into the still-rare strength training gyms of the time.

Weight training became increasingly popular in the s, following the release of the bodybuilding movie Pumping Iron , and the subsequent popularity of Arnold Schwarzenegger.

Since the late s, increasing numbers of women have taken up weight training; currently, nearly one in five U.

women engage in weight training on a regular basis. Men and women have similar reactions to resistance training with comparable effect sizes for hypertrophy and lower body strength, although some studies have found that women experience a greater relative increase in upper-body strength.

Because of their greater starting strength and muscle mass, absolute gains are higher in men. Orthopaedic specialists used to recommend that children avoid weight training because the growth plates on their bones might be at risk. The very rare reports of growth plate fractures in children who trained with weights occurred as a result of inadequate supervision, improper form or excess weight, and there have been no reports of injuries to growth plates in youth training programs that followed established guidelines.

As a result, supervision of minors is considered vital to ensuring the safety of any youth engaging in strength training. Aging is associated with sarcopenia , a decrease in muscle mass and strength.

The activities involve using your body weight or working against a resistance.

You should try to do 2 sessions or more of muscle strengthening exercises a week. Exercises that improve leg strength, balance and co-ordination can help people maintain and improve their muscle strength and avoid falls as they get older.

For an activity to be muscle strengthening, it needs to work your muscles to the point where you may need a short rest before continuing. For example, if you're lifting weights, you'd have to put the weight down after doing a number of lifts before carrying on.

Flexibility exercises are activities that improve the ability of a joint to maintain the movement necessary for carrying out daily tasks and physical activity. Muscle-strengthening activities help maintain the ability to perform everyday tasks and slow down the rate of bone and muscle loss associated with ageing.

Health professionals believe that improving your flexibility can improve your posture, reduce aches and pains, and lower your risk of injury. Good flexibility can also help you to continue carrying out everyday tasks.

It's a good idea to do muscle-strengthening activities that work all the major muscle groups legs, hips, back, abdomen, chest, shoulders and arms on 2 or more days a week.

No specific amount of time is recommended, but a typical training session could take less than 20 minutes. Exercises should be performed to the point at which it would be difficult to do another repetition without help.

A repetition is 1 complete movement of an activity, like lifting a weight or doing 1 push-up or 1 sit-up.
