i usually rest 5 min -6 1/2 each set,i know this is long,
a few exceptions are the second half of my bicep workout,because i feel the muscles will die out quicker if i rest too long,and also d.b bench i dont rest as long,but on other excercises such as bench,behind the neck ,squat ,bent over row etc, i feel if i dont get at least 5 min,i will not do as many reps as if i rested less,i konw i have poor endurance, but even when i use to have great endurance i still did the same thing and i would do less then too if i rested too little

B True

If you're looking to increase strength make your rest even shorter 60 seconds, do lower weights and more reps.

It's true that if you rest longer between sets, you can lift more. You can also get the same effect by doing less repetitions. One warm up set of 10 - 12 reps, then no more than 6-8 reps. You'll be conserving your energy for your heavier weights, but you should be able to shorten your recovery time.

Try to stay out of idle conversation when you're working out. If you have a partner or 2, just alternate in and out of your sets, and help each other to stay motivated to move quickly. If no partner, you have even less to discuss between sets.

The object is not to train as long as you can, but to train smart. Lengthy workout sessions, you tend to overtrain. I've been guilty of this myself many times.
