Tendon and articular cartilage are both avascular tissue, fed by load and repaired by load. Resting them is not protection but degeneration — the signal that triggers repair is, counter-intuitively, the loading itself.
Every muscle contraction moves glucose into the cell without needing insulin, via the GLUT4 route. That is why a post-meal walk flattens blood sugar, and it is the mechanism that earns walking the word 'medicine'.
Regular resistance training is the underrated item here: it preserves muscle and improves metabolic health — the exact opposites of the confounders that depress testosterone. Not a testosterone-boosting protocol, just fixing the foundation.

Cooney 2013 Cochrane d = -0.62 (moderate-large), matching SSRI monotherapy. Mechanism: myokines (irisin / BDNF) + DMN reorganization + HPA normalisation. Acceptable as first-line for mild-to-moderate MDD.
Muscle contraction recruits GLUT4 via AMPK, insulin-independent. DPP 2002 NEJM: exercise + diet → T2D progression risk ↓58% (better than metformin). Reynolds 2016: post-meal 15-min walk → postprandial glucose ↓30%.
Isometric exercise (handgrip / wall sit) SBP ↓10 mmHg (Smart 2019 meta) — exceeds ACE inhibitor monotherapy effect. Post-exercise hypotension: one moderate aerobic session → 22h sustained ↓5-7 mmHg.
Kredlow 2015 meta: sleep latency ↓13 min, TST ↑19 min, PSQI ↓0.31 SD. Comparable to CBT-I, exceeds melatonin. Morning training best; post-9pm high-intensity disrupts sleep.
EWGSOP2 + Liu 2009 Cochrane: RT in sarcopenic populations shows SMD 0.84 large effect. RT + protein is the only evidence-based intervention; no drugs are approved.
