Bulking

Bulking (Calorie Deficit) involves consuming excess calories to build muscle. Bodybuilders commonly use bulking as a way to increase their overall muscle mass/size.

“Looking big bro, looks like the bulk’s going well.”

“Thanks, I’m planning on cutting next month when I’m done bulking!”

MPS

Muscle protein synthesis (MPS) is the process of producing new muscle protein. MPS is an important component when maintaining or gaining muscle mass.

“The MPS must be greater than the MPB in order to build muscle mass.”

Cutting

A cut is a period of burning more calories than you consume, as a means to lose overall body fat/weight while maintaining as much muscle mass as possible.

“Looking shredded dude, you cutting?”

“Yeah bro! 3 months in so far.”

MPB

Muscle protein breakdown (MPB) is an important metabolic component of muscle remodeling, adaptation to training, and increasing muscle mass.

“If MPS is greater than the MPB, you will gain muscle mass.”
