Just to add, anybody doing the test could/should consider it a mini-workout in and of itself...going all-out
for 6 minutes with no rests isn't easy at all.
Also, where it states 10, 12, 15 reps etc for each of the designated minutes throughout the test, that means you should spread the reps out over the minute, not just get them over with as soon as possible so that you end up with rest
So, for example, if you're expected to do a warm-up minute of 10 reps, make sure to do a rep at around every 6 seconds. For this, it helps to sit and work out how many reps you need to fit in to a small time period of say 6-10 seconds etc, in order to have a continual snatch going on.
Obviously, once you get to the 6th minute and have warmed-up, via the other 5 minutes work load, then hit it hard and don't stop until that timer/clock hand strikes 0...that is the hardest minute to do and you will
flag badly but keep ploughing on, don't short change yourself on the reps.
