The more muscles you work, the better it is in terms of results. Working a small muscle group like your arms can get pointless pretty fast due to overtraining in the beginning. You might feel like am a bit inclined away from isolation workouts, which are an essential part of any body building routine. The problem is, not everybody needs to do it. As far as a complete beginner goes, he first needs to build a strong base in terms of strength and muscle mass before you can proceed to actual body building and the long bulking-cutting cycles.
Get enough rest. While some people exert too little effort and easily lose patience, others also try too hard and over-train. You need to rest in between workouts. The muscles you stress during a workout should get about 72 hours of rest so that they can have the opportunity to recover and grow. You also need to get enough sleep very night. That means getting 7 hours of sleep minimum.
About 6 months ago, while playing basketball, I landed awkwardly and tore my A.C.L. My doctor told me that if my legs were stronger, my injury would have been less severe. Just two months ago, I started to train my legs again, squatting just the bar and eventually working my way up. I've still got a long way to go before I can play basketball or even run again.
The bench press or dumbbell bench-press is performed while lying face up on a bench, by pushing a weight away from the chest. This is a compound exercise that also involves the triceps and the front deltoids, also recruits the upper and lower back muscles, and traps. The bench press is the king of all upper body exercises and is one of the most popular chest exercises in the world. It is the final exercise in 'The big 3'.
Use a split system. If you have never trained with weights, or have taken a significant break from weights, I do not recommend training at maximum intensity right away. Training to failure during the first crucial work outs will result in tremendous muscle soreness and you may never return. Start slowly by doing a full-body work out consisting of three or four sets of lighter weights for every major muscle group. After the first couple weeks, you can increase your intensity and move onto a split system. An example of a three-day split might be:
The Old School bodybuilders would split the body up in several muscle groups in order to work each muscle group adequately. A six day split would separate the muscle groups into three separate days and each muscle group would be trained twice a week. For example, bodybuilders would train chest and back on Monday and Thursdays, legs and abdominals on Tuesday and Friday and shoulders and arms on Wednesday and Saturday.
In either phase, don’t exceed 1 gram per pound of body weight of protein (2.2 grams/kilogram). A little more probably won’t hurt a healthy person, but chances are, based on the science of protein requirements for athletes, it won’t help either. It will only cost you in expensive supplements or food. Any hint of kidney disease and you would need to be cautious about excessive protein intake. Consult your doctor for advice if this applies.
When lifting it is essential to focus your mind completely on the muscle group you are attempting to work on. This makes sure that you are actually using the target muscle to lift the weight rather than accessory muscles or even momentum. This skill will develop with time, and as you progress in making that mind to muscle connection, your workouts will become much more productive and efficient.
