Adherence

Unsupervised resistance training in men with >3 years of experience fails to produce significant changes in fat-free mass or fat mass over 15 months.

If you have been lifting seriously for over three years and aren't seeing changes in muscle or fat despite training 3-5 times a week, your current self-directed approach has likely plateaued. You likely need professional guidance to systematically adjust training variables and nutrition, as self-regulation alone is insufficient for continued progress in advanced lifters.
