exesion
like the guys said. water, water, water and lots of exercise.
however rather than once a day till it kills you (crunches)
try doing 2 or 3 sets once a day, then rest that muscle group a day, and do again, repeat.
hanging on bars and doing leg lifts is also good.
for your weights, work a system so that you exercise each muscle group.
every 2 or 3 days.
work on abs and arms one day and calfs, and neck another.
try to allow a day rest basically to each muscle group worked.
the rest bit, is very important as it allows the muscle to grow and heal at the same time.
remember that when lifting for bulk, that you are ripping the muscle down and building it back up in a sense.
so a days rest between each serious workout is important.
also remember not to tire yourself out too much as you are a dating animal now
take care minir
