20 Push-Ups Every Day for 90 Days — Here’s What Happens to Your Body (Science)

Описание: What really happens if you do 20 push-ups every day for 90 days?

Most people think daily push-ups “destroy your shoulders” or lead to overuse injuries. The truth is more interesting — and it comes down to form, dosage, and adaptation.

In this 58-minute deep dive, you’ll learn what daily push-ups can do for:

Strength & muscle growth (satellite cells, protein synthesis, neuromuscular efficiency)

Posture & core stability (deep core activation, anti-extension strength, spinal alignment)

Cardiovascular health (why push-up capacity correlates with heart health)

Insulin sensitivity & metabolism (GLUT4 activation and daily glucose control)

Hormones & stress (testosterone-to-cortisol ratio and hormetic stress)

Bone density & joint resilience (Wolff’s Law and load-driven remodeling)

Brain function (myokines, BDNF, focus, and stress regulation)

Most importantly, you’ll learn how to do this safely:
✅ 45-degree elbow angle
✅ hands under shoulders
✅ core tight + glutes squeezed
✅ stop if it’s sharp pain (not soreness)

If you can’t do 20 yet, start where you are. Do 5. Do them on your knees. Build the habit — then build the reps.

Comment “DAY 1” if you’re starting today.
