i really dont mind if he lifts heavy weights but point is he
CANNOT do it and needs help.
in IPF competitions if the spotter touches the bar when ascending
even without any assitance in lifting , it is NOT considered a
legit lift.Refer to IPF rulebook.
once i helped him with 90kg stuck on his chest on the incline
bench, he thanked me in a very pissed off manner. 
The spotter is only there for safety purposes, not to help you lift
from rep 1 to rep 5
In conclusion
Dont bite off more than what you can chew.
i think dean is right. that guy needs to find his one RM and
work on it depending on what he wants to train
Yea he will probably use the 1RM that he and his spotter lifted
together.
