It wasn't that long ago for me, my 1st gym visit was a mix of
lost and joy.
Joy, because i found out there's this nice gym in my school which i
can use for free and they play my favourite radio station class 95
lol.
Lost, coz i dunno what to do and dunno which exercises trains what
so much so that i had to slowly read the instructions on each
machine then try to emulate the instructions lol.
By the way, i still dunno the weight units they don't seem to be kg
i just roughly adjust by trial and error until i'm comfortable with
them.
I ignorantly camped there for nearly 1 and half hour meddling with
the machines only and looking around to see how the pros use
different exercise.
Until now i just do exercises i see but still dunno the formal term
lol.
after 1st visit, took me a week to recover from the sore and pain
then i read here that must limit 45-50 minutes so that we don't
overburn
