HIIT vs Lifting

For T — one wins over years.

Both spike T

Acute rise of 15–40% for 15–60 min.

Only lifting builds

Muscle mass = higher resting T.

Muscle = AR density

More androgen receptors to act on.

Chronic difference

5–15% higher resting T in lifters.

HIIT still helps

1–2 sessions/week for conditioning.

Overtraining trap

6+ hard sessions/week suppresses T.
