I aim to take in 1.5 grams of protein per pound of bodyweight per day and divide that total number by the number of meals I'm going to eat. For me, that means I eat approximately 360 grams of protein each day. I spread this across 6 meals, which turns out to be approximately 60 grams of protein per meal, depending on the day. The reason I eat protein frequently throughout the day is that muscles are built outside the gym. I may spend an hour or two training each day, but it's the other 22 hours or so when I earn my results.
Reaching failure matters because tension matters. Failure is when the muscle cannot generate anymore force. Which means one applied (worked out) enough tension through the muscle to just want to give up. And guess what? Carrying groceries can do this for some. Why? We are all at different strength levels. So don’t worry about other people and what they can or cannot lift. I say this because FAILURE can be achieved with either light weights or heavy weights.
Most typical bodybuilding programs have way too many sets and reps and use the wrong exercises. However, if you lower the total volume, go heavier, and use compound movements as I’ve outlined above, there is nothing wrong with a body-part split for advanced lifters. In fact, it’s often less stressful to the joints than your average upper/lower split.
When these muscles are under constant tension because of ergonomics and habitual postural positioning, they may become tight and shortened. This can result in pulling forward on the lumbar vertebrae, creating hyperlordosis and causing the pelvis to tilt anteriorly. This is commonly seen in people who maintain a seated position for a prolonged period such as office workers, computer programmers, and others who find themselves sitting at a desk for hours every day. It is important to provide education on proper ergonomics, movement, and self-care to these individuals.
