so diffcult leh..i think nd a proper trainer only can do this...izzit got other way ?

just wan to ask..if i do chest press by machine..i take 12 kg..then i do it 30-40 time per set..do it 3 set ..can ?

or take 19kg, do it 20 time x 3 set? izzit the same ?

coz currently i more focus on chest..

then every morning got pumping..12 times x 5 set..can ah ?

if have a friend to train beside u..i think is more easy..at least can support you when u go to climax
