Cardiovascular improvements appear in 2–4 weeks; strength gains in 4–8 weeks (initially neural); visible body composition changes typically 8–12 weeks. Detraining begins after roughly 2–3 weeks off.
A realistic sequence: energy and mood improve in 1-2 weeks, strength in 4-8 weeks, visible change in 8-12 weeks, and clothes fitting differently often before the scale moves much.
Consistency over months beats intensity over weeks. Most people who fail do so by starting too aggressively to sustain.
