The first month always looks good. The weights go up, the clothes loosen, motivation is free. Then week four arrives: one session missed, one done at half effort, and a weekend that eats the whole week's deficit. Nobody wrote the numbers down, so nobody noticed the bar hasn't moved in three weeks.
So you find a second programme. Then a third. Each one looks more serious than the last, and each one ends in the same place.
The problem was never information. You already know to sleep, eat protein and lift heavier. What's missing is one person who looks at your numbers every week and tells you the single thing to change next week.
