Now come on. I really shouldn't even have to tell you this one. But you wouldn't believe how many times I'm talking to somebody and they say that they're cutting right now. What's the problem with that? Nothing... except for the fact that after we're finished talking they whip out a ho-ho or something and start scarfing down their junk like no tomorrow. And then they go and tell me it's their dinner!! What's up with that? Either they can't handle the bodybuilding life, or they really, really need to do some serious research.
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.
Believe me, whatever you're doing, you can do more. And no, you won't overtrain; you'll just advance faster when you push your limits. I used to think squatting 405 pounds for 10 reps was great. Now I can do 405 for 25 reps and it's okay, but I know I'm going to get up to 35 reps. Don't be afraid of more weight and more sets; just push a little more each and every workout (even adding 2.5 pounds is great). The greatest athletes in the world have done things that everyone thinks are crazy, but these are the same people breaking world records. Trust me, you can always do more. Train hard, train harder!
They found little difference in muscle growth between those who worked in the hypertrophy range and those who lifted lighter weights for 20 to 25 reps (i.e., deep into the so-called “endurance range). As long as the subjects trained to “volitional failure” — the point at which they couldn’t perform another rep with good form — they got bigger and stronger. (Editor’s note: Volitional failure is different than absolute failure, which is when you simply can’t perform another rep. More on that in tip number six.)
After session 12, consider whether you need to increase the weight for any particular exercise. If you can comfortably do more than the RM of 12 exercises, increase the weight by a modest amount, say two pounds or a kilogram for isolation exercise muscles such as triceps and biceps, and 5 pounds or 2.5.kilograms for compound and large muscle group exercises like squats and deadlifts. When using dumbbells, this would apply to each one. Don’t increase the number of sets beyond 3 at this time.
