Weightlifting

I just added the link to the pdf manual from the Impex site which includes detailed assembly instructions.

no it does not, unless you happen to injure yourself in a way that it affects a growth plate

ma brother jus turned 14 he weighs 160 and benches 195 1 rep

1075 lbs (488,64 kg)

This was done by Ryan Kennelly in 2008.

A ten year old should not be focused on getting ripped but staying healthy is important. If they are overweight, or just unhealthy they should be encouraged into physical activity, preferably a sport they enjoy

One of the core exercises of power lifting and strength training in general, the bench press develops the pectoralis major and minor (large muscle group making up your chest) and triceps primarily, but also helps develop the anterior deltoid (front shoulder muscle), and the serratus anterior, a muscle on either side of the body that flares out slightly from the bottom of the armpit to the middle area of the ribcage. The serratus anterior is also known as the "boxer's muscle", because this muscle is utilized by pushing the scapula forward and around the rib cage when executing a punch. The forearms will also be developed to a lesser degree because they act as a stabilizer when performing the bench press. Adjusting the position of one's body, such as sitting up at a roughly 45 degree angle (incline bench press), or lowering the bench and lying back with the head below the horizontal position of the hips (decline bench press) help isolate the upper and lower portions of the pectoral muscles, respectively. The width between one's hands when gripping the bar is also significant; a wide grip concentrates force in the pectorals, while a close grip concentrates force in the triceps.

The bench press is an excellent upper body exercise and crucial to developing power and definition in the chest, shoulders and arms. Large chest and shoulder muscles also help define the so-called "V-shaped" torso in a man, which women across nearly all cultures cite as a physically/sexually attractive trait. And remember: safety first! Always make sure to have a spot and I highly recommend against benching alone, lest you want to asphyxiate yourself or knock out your front teeth! If you don't have access to a bench press or are by yourself, push-ups will suffice, for the most part. Just make sure to do them often and to push yourself to do more.

Frank Zane was at his best between the age of 35-40 years of age and a body-weight of 190lbs. That said, Mr. Zane could have bench pressed twice his body-weight or 380lbs., squatted 2.5 times his body-weight or 475lbs. and deadlifted 3 times his body-weight or 570lbs. Frank Zane trained for muscle definition and not pure strength like a powerlifter. Had Mr. Zane trained exclusively for strength, then it is not unreasonable for him to have achieved a 400lb. bench, 500lb. squat, and 600lb. deadlift!

With your muscles usually hands and arms.

It also means leg training as well. You would want to use dumbells, barbells and weight machines to train your entire body. Arms, legs, chest, shoulders, back, abs. Each time you weight train, or as the question says "lift weights". You need to decide what are the goals you are trying to accomplish.

A dumbbell will generally require more strength than a barbell. Once you push up a barbell it balances out but with a dumbbell you have to keep it balanced the whole time which requires more strength. One is not "better" than another, just different. Do both if you can.

The bench part, with a comfortable, heavy-duty back pad, is 68 inches in length.

You should do the amount of press-ups that make your muscles feel exhausted. This number will change every week, but it helps you grow bigger muscles.

Yes, but only temporarily. When lifting weights your body pulls blood from other areas are redirects it to the muscles being exercised. Your penis is loaded with blood vessels so the lack of blood causes it to shrink. The blood normally returns shortly after exercise. It's normal.

Leonid Taranenko of the USSR lifted 266.0Kg in the Clean & Jerk in 1988. This remains the heaviest ever Clean and Jerk recorded in competition.

Why not use weights? This matters actually. Weights are used because their weight provides resistance to movement forcing you to use more strength with triggers the building of muscle. How often you do these excersizes, how much resistance/weight you use, how long a session is and how long you hold a position and how many reps you do all affect what sort of muscle you will put on. You will either strengthen existing fibers or create new ones. Usually people do both. You can end up bulking up very little, some or a lot (women and men will have different results.) If you want to avoid the expense of weights use water or sand in bottles or cans of food. These have weight and are cheaper. I would advise getting real weights tho, you can find them for $1 per lb so it is worth the expense to have something easier to hold. If they just aren't your thing try rubber bands, they sell special ones that also provide resistance like weights but instead of lifting something heavy you stretch something. Or you can use your own weight, crunches, push-ups, pull-ups, running and other equipment-free exercises make use of your own weight to provide the resistance. I like a combination, keeps things fresh and helps ensure that I am working all my muscles fairly evenly. Talk to your doctor or a fitness counselor for more information about a good routine for yourself. :)

i'd recommend just 1 minute

There is some disagreement on this one. one answer is Scott Mendelson, who is the current word record holder for the heaviest unassisted 1 REP bench press with a press of 1008 pounds. Another is Paul Anderson, who still holds the Guinness record of 6,270 pounds.

Don't know what the answer is for the average, but I will be 63 this year and can bench 200 lbs.

Depends on how much you exercise.

"May I know how long does it take for my muscles to grow visibly?" Well, as a professional fitness personal trainer, I get variations of this question from almost every new client. So how can I answer that question because there are also many variable factors like for instance, if you are fat, you can't see your muscle growth unless you take the fat off or what is being visible is subjective from person to person. For the hardgainers (people who have difficulty in gaining weight), gaining weight or muscles can be very a difficult and tedious process without professional help. For the genetically endowed, muscle growth can be very fast while some others may make only little progress or even no improvement at all (the latter being lack of muscle building education). Therefore, if you are wondering how long does it take to grow muscles, then I must be forthright with you and tell you that there is just no direct answer. However, the good news is that if you eat and exercise correctly, your muscles will definitely grow, even for hardgainers. Unknown to many people, muscles do not grow in a linear process but in a series of spurts and as such, no matter how hard you workout your muscles and how much you eat, your muscles will probably not grow at predictable pace. I know that this fact will surprise many people. There are many more reasons influencing your muscle growth and not everyone will build muscles at the same rate even if they are working out with the same weight, exercises and eating the same food. Some people are genetically predisposed to growing muscles and will see amazing results after only just a few months. We all know that the Mesomorphs (sporty body frame) will grow muscles faster than the Ectomorphs (slender body frame). Your rate of muscle growth will also depend largely on how close you are to the upper limit of what you are naturally capable of in terms of growing muscle mass. This phenomenon is known as the adaptation ceiling. What this means is that closer you are to this upper adaptation limit, the slower your muscle will grow. To put it in simpler terms, someone who has been working out with weights for a few years will grow muscles much more slowly than a novice who is new to weight lifting. Another fact is that it is not uncommon for people to gain body fat when they are growing muscles. The amount of fat you gain will depend on how much you eat, what you eat and also on how lean you were when you first started to fuel your muscle growth with what you eat. Eating to propel muscle growth is commonly referred to as "overfeeding". Numerous studies have shown that during a period of overfeeding, you will gain more muscle and less fat if you are the lean body type. During the cutting phase to get rid of body fat to show muscle definition, it is known that fatter people tend to lose more fat and less muscle when they cut, but the leaner ones will find it harder to lose fat without losing muscle. Why does this happen? Well, it could be merely be psychological. Take for example when you have worked very hard to get your well defined six-pack abs, then you will not want to put the fat on again and obscure your hard earned abs and thus you may be reluctant to eat the amount of food necessary to gain significant muscle growth. Make sense? Another reason could be hormonal imbalances as some studies do show a correlation between low body fat and low testosterone (male hormone) levels. If your testosterone is low, it is also difficult for you to grow muscle mass. So how long does it take to see muscle growth will depend very much on your genes and many other factors besides merely exercising with the proper workouts and eating correctly.

They were just born that way.

It is cheaper than using, for example, stainless steel, and really only has to be heavy.

That depends how many pounds you are lifting, how often you lift, and how many reps you do. I would say about 4-10 weeks.

A bench vise is a clamping tool used for construction projects. They allow the user to use saws, drills, sandpaper, and many other tools safely and easily.

Smoking constricts your blood vessels which affect their ability to transport oxygen and other molecules (glucose) to your muscles which will effect their ability to contract. Also smoking makes it harder for your lungs to absorb oxygen.
