Age?

Well, i've started gyming it and body building for 5months... When i told my friends and stuff they began questioning me :
 
Weight lifting at an early age can stunt your growth?
 
It makes your penis small!?
 
I'm 16 years old, should age be a problem? Does it make your knob smaller? :O
 
(sry if covered, im new)

typical myths that float around the locker room...but no they arent true...your penis is not going to get smaller because you lift weights, and i personally grew the most while lifting...if you notice, its the people that dont workout, or have realized that they have the lack of motivation to workout, that spread these rumors...they're jealous.

Let the pain come over you, but never overcome you.
If you don't live for something, you'll die for nothing.

No, have to disagree with jkoemel.

If your growth plates have not completely formed and you lift too heavy, you can hurt your growth.  You cannot rely on anecdotal evidence ("I still grew" is not objective nor scientific--what if you would have grown more?  Has your whole body been examined with imaging techniques for bone damage)?

However, 16 is probably ok.

If Mr. Winky shrinks, that will make medical history.

"If there's nothing else that's relevant, I'll be leaving now"

"Today's mighty oak is just yesterday's nut that held its ground"

Speaking of anecdotal...

If your growth plates have not completely formed and you lift too heavy, you can hurt your growth.

Can you link to a scientific journal or study that has shown this to be true?

Ok, I'll be big enough to admit that I was wrong--well, not totally wrong, but not correct.  Until you are physically mature, your lifting regime will be different than someone on a all-out mass building expedition.

Here's what the Academy of Pediatrics says.  Note the following:

"A limited number of case reports have raised concern about epiphyseal injuries in the wrist and apophyseal injuries in the spine from weight lifting in skeletally immature individuals. Such injuries are uncommon and are believed to be largely preventable by avoiding improper lifting techniques, maximal lifts, and improperly supervised12,15,16 lifts."
And recommendation no. 2, "Preadolescents and adolescents should avoid competitive weight lifting, power lifting, body building, and maximal lifts until they reach physical and skeletal maturity.")--sorry it pasted in so ugly.

Strength training (also known as resistance training) is a common component of sports and physical fitness programs for young people. Some adolescents and preadolescents may use strength training as a means to enhance muscle size and definition or to simply improve appearance.
Strength training programs may include the use of free weights, weight machines, elastic tubing, or body weight. The amount and form of resistance used as well as the frequency of resistance exercises is determined by specific program goals. Table 1 defines common terms used in strength training.

      BENEFITS OF RESISTANCE TRAINING In addition to the obvious goal of getting stronger, strength training programs may be undertaken to improve sports performance, rehabilitate injuries, prevent injuries, and/or enhance long-term health. Studies have shown that strength training, when properly structured with regard to frequency, mode (type of lifting), intensity, andduration of program, can increase strength in preadolescents and adolescents.1-4 muscle size, or power are lost after 6 weeks if resistance training is discontinued.5 Maintenance exercises may offset these losses, but specific recommendations for maintaining strength gains have not been defined for preadolescents and adolescents. Gains in strength,
In preadolescents, proper resistance training can enhance strength without concomitant muscle hypertrophy. Such gains in strength can be attributed to neuromuscular "learning," in which training increases the number of motor neurons that will fire with each muscle contraction.2,6,7 This mechanism helps explain strength gains from resistance training in populations with low androgen levels, including females and preadolescent males. Strength training can also augment the muscle enlargement that normally occurs with pubertal growth in males and females.3,6,8,9
Strength training can improve an adolescent athlete's performance in weight lifting and power lifting. Strength training is a common practice in sports like football in which size and strength are desirable. Despite theoretical benefits, scientific studies have failed to consistently show that improved strength enhances running speed, jumping ability, or overall sports performance.6,10
Evidence that strength training programs help prevent sports-related musculoskeletal injuries in preadolescents and adolescents is inconclusive.11 Furthermore, there is no evidence that strength training will reduce the incidence of catastrophic sports-related injuries.
    RISKS OF STRENGTH TRAINING The US Consumer Product Safety Commission, through its National Electronic Injury Surveillance System (NEISS), has estimated the number of injuries that are associated with strength training equipment. The NEISS data neither specifies cause of injury nor separates recreational from competitive weight lifting injuries. From 1991 to 1996, an estimated 20 940 to 26 120 injuries occurred each year in individuals under 21 years old.12 According to NEISS data and other studies,13 for 40% to 70% of all injuries. The lumbar back is the most commonly injured area.11,14 muscle strains account
A limited number of case reports have raised concern about epiphyseal injuries in the wrist and apophyseal injuries in the spine from weight lifting in skeletally immature individuals. Such injuries are uncommon and are believed to be largely preventable by avoiding improper lifting techniques, maximal lifts, and improperly supervised12,15,16 lifts.
Strength training programs do not seem to adversely affect linear growth and do not seem to have any long-term detrimental effect on cardiovascular health.2,417-19 Young athletes with hypertension may experience further elevation of blood pressure from the isometric demands of strength training.8
    STRENGTH TRAINING GUIDELINES A medical evaluation before commencing a formal strength training program can identify possible risk factors for injury and provide an opportunity to discuss training goals, techniques, and expectations. Risks involved with use of anabolic steroids anddy-building supplements are appropriate topics for discussion with any adolescent interested in getting bigger and stronger.20,21 other bo
If children or adolescents undertake a strength training program, they should begin with low-resistance exercises until proper technique is learned. When 8 to 15 repetitions can be performed, it is reasonable to add weight in small increments. Exercises should include all muscle groups and be performed through the full range of motion at each joint. To achieve gains in strength, workouts need to be at least 20 to 30 minutes long, take place a minimum of 2 to 3 times per week, and continue to add or repetitions as strength improves. There is no additional benefit to strength training more than 4 times per week.5 weight
Young people who want to improve sports performance will generally benefit more from practicing and perfecting skills of the sport than from resistance training. If long-term health benefits are the goal, strength training should be combined with an aerobic training program.

Gzinkl always goes all out and proves his ****, I love it! Great job dude, I admire you :)

That throws up another question, just out of curiosity:
They say that exercises like Squats and Deadlifts liberate growth hormones. If this is so, could it cause excessive growth in teens???
 
It's really just out of curiosity. Since I'm 39 now, I guess I'm slightly beyond that age.

Destiny is a game you can't win. If you act accordingly, you can lose it the best way possible.

I can relate to the 'skellatally imateur' comment, as sometimes while benching - it's not that i cannot lift the weight, but i get really bad pains in my right wrist which obviously inhibits the lift. Usually with the higher weights - 60kg +
 
Another question while im here if thats ok ?
 
As im in England, our gym operates in Kilograms (kg) and i'm curious as to what im lifting in relation to others here operating in lbs. Anyone link to a converter? or tell me some way of working it out?

A pound is 0.435 Kg. 60 Kg: 60 / 0.435 = 137.93 lbs

Destiny is a game you can't win. If you act accordingly, you can lose it the best way possible.

no it's more like 1kg = 2.2lbs, so therefore 60kg = 132lbs, you're off by about 5lbs :D

weight lifting does not make your penis smaller.  Weight lifting doesnt stunt your growth, its the supplements that you take during lifting that may stunt your growth at an early age.
