there is a buddy system. so for instance, tag number 71 to 75 will do push up first while tag 76 to 80 will count for them. then tag 76 to 80 will do while tag 71 to 75 count.
the assistant is the one that put his fist below the chest and the assistant will also do the counting out loud.
there will be a PTI beside you who make sure that you are doing standard push up and will tell you on the spot if the push up is no count but the assistant will keep counting out loud without subtracting the no count away.
the push up is actually not that hard but is just very tiring. i managed to do 49-4=45 during my ippt this evening.
i am the short and skinny underweight type whereby the last time i exercise was December 2013 during my RT. what i did was to do 20 standard push ups everyday for the past few months. and then once 20 standard push ups is chicken feet, i start doing 20 standard and fast push ups. and then once there is chicken feet, i increase to 30 standard and fast push ups.
but in the end i fail my ippt cos i ran/walk 20min for 2.4km.
0 to 15 points ==> 16 to 30 points ==> 31 to 50 points ==> standard ippt pass
let's say if your very first ipt-ippt you get only 8 points. so the PPT for this year is "16 to 30 points". then next year your PPT is "31 to 50 points". and then from next next year onwards your PPT is standard ippt pass forever.
if your very first ipt-ippt you get only 25 points. so the PPT for this year is "31 to 50 points". and then from next year onwards your PPT is standard ippt pass forever.
if your very first ipt-ippt you get only 35 points. so the PPT for this year is standard ippt pass. and then from next year onwards your PPT is also standard ippt pass forever.
so basically everyone is screwed within 3 years.
