doing 10-12 reps to failure is a bit extreme. It's hard doing high
reps and it's hard doing to failure.
I get a bit nauseus when I do more than 7 reps. If I do more than 7
reps to failure, then I find that it is tiredness that makes me 'fail'
on the last , and I feel a bit nauseus. Whereas if I do like 4-6 reps,
I find that I don't have the strength to squeeze out another rep - that
is a nicer feeling, I don't get nauseus when I do that.
Usually if i'm doing high reps I wouldn't want them too intense,
because high reps are tiring enough anyway.
Besides that - as ppl have said, blood sugar may be an issue, as well
as rest between sets. One cause of tiredness is the high reps made
worse by the fact that you are going to failure. The fact that your
tiredness is so serious, may also linked to blood sugar. So try
Lucozade in between sets, and rest for a long time in between sets.
I tend to rest for about 5 minutes, I can feel if i'm very tired from a
set.
Significantly, you appear to have a problem that weight bearing
exercise is lowering your pulse. That is probably why running and
doing more weights is giving you a second wind. Because the running is
increasing your pulse again. But have lucozade or something to raise
your blood sugar before and after a set of weights.
I'm no expert, but maybe the high reps are literally making you tired,
they are sapping your energy, and then you go and push that to failure
and that just makes it worse.
I am sure that if you lower the reps to say 6 reps, then you won't get
nauseus. I know that 12 reps would make me nauseus. You don't need to
go to failure. Weight lifters never go to failure all the time, they
vary their intensity. See how you progress without going to failure at
all, and try 6 reps not 10-12. So that you don't have the strength to
do another one, but are not too tired and sick to do another one.
Those are very different feelings. I even get tired with 7 reps, I
only really enjoy it when I am doing about 4 reps. I think that you
would see a dramatic improvement going from 12 reps to 6 reps - and
lower intensity - when beginning you shouldn't go to failure. I would
never go to failure at such high reps, because failure via tiredness is
horrible. Even when past the beginner stage, nobody goes to failure
every workout - they vary the intensity.
excuse the repetition!
