Heavy lifts do more than strengthen muscle. Meta‑analyses of resistance‑training trials show that 8–12 weeks of progressive weight‑lifting raises maximal power by ≈ 30 %, but it also boosts basal dopamine and self‑efficacy scores—key predictors of confidence and positive body image. Observational work in young and middle‑aged adults links regular strength work to higher perceived attractiveness and leadership ratings, likely because lean‑mass gains improve posture, shoulder‑to‑waist ratio, and facial vascular tone. So “I lift weights and eyebrows.” Every set you grind out not only readies your body for heavier loads, it primes the kind of presence that makes people take notice.
