HE USED DBELL FOR CHEST AND FREE WEIGHT CURLS,LATERALS..
It's best to use whatever gives you the best muscle contraction/activation and this machine bench at my gym gives me a very very good pec contraction and lucky me it's a pin machine so I don't have to load fucking plates on it but if all goes as planned I will stack it out within 4-6 weeks so then I will have to go to plate loaded pec machines
Same with the lat work, a plate loaded lat pulldown gives me a better lat contraction than the standard pulldown so I'm using it
As far as the dips go I'm loading 3 10 kg plates which is 30 kg but I can load it up with 6 plates max, 8 plates nope would not be practical, but 6 10 kg plates is 132 pounds which would be a pretty good feat although mentzer told me he was able to dip with an added 180 pound bell, the bells at my gym only go up to 50 kg 110 pounds
I showed my Brazilian friend this pic and he said I am looking fuller than before so he knows what he is talking about and he isn't even interested in training or BB 😂😂😂
