Fitness Myths
Fitness culture is full of confident claims. These are careful, practical responses — not a promise that every individual will respond the same way.

No. Muscle is built from training, enough protein, enough energy, and time. A protein powder can make hitting a daily target easier. Creatine is one of the better-studied optional supplements for some people. Neither is required. Food and training come first.
Not by default. Long, exhausting cardio stacked on top of hard lifting, poor sleep, and low calories can make recovery harder. Moderate walking or short conditioning sessions usually sit fine next to strength training. The problem is usually total stress, not cardio as a category.
You cannot choose the exact place fat comes off first. Local exercises can strengthen a muscle. Fat loss is driven mainly by a sustained calorie deficit over time, and where it shows up is largely individual. Crunches do not preferentially empty abdominal fat.
No. Many people make excellent progress on three or four training days. Rest days are part of the program. Daily walking is often useful. Daily max-effort lifting is not a requirement, and for most people it is a fast way to stall.
No. Soreness means you did something unfamiliar or high in eccentric stress. It is not a reliable scoreboard. You can grow without being sore, and you can be sore without a good program. Progress in load, reps, or quality over weeks is a better signal.
