You should always be learning. The fitness industry is always changing, especially with digital media giving it out anytime.

Most people are just fat and because most bodybuilders juice, they can get away with eating what they want and just monitoring calories. It's a horrible misconception and often sends people down a path of fat gain that might ruin their motivation and drive. Fat cells never go away once created.

My motivation was I wanted to look like my favorite super heroes when I was a kid. Pretty cheesy, but that is what got me started.

I don't think it's ok to judge others and put people down. However, it should be ok to be concerned about the health of someone which could leader to major problems in their future.

My favorite muscle to train is TRICEPS! Always has been my stongest muscle group as well.

Having a CORE main focus is the key to being able to stay determined. Most people only set small goals and when they accomplish them... it's hard to stay on track as they are not trying to achieve anything else.

The biggest mistake I see people make is they are not on the right program. You should be circuit training and performing cardio 4-6 days a week (depending on time).
