Jørgen "Jet" Johnsen's top tips
- Train your core like a muscle, not an afterthought, 2-3 hard sessions a week
- Brace before you press, pull or squat, ribs down, breathe into your belt
- Mobility isn't stretching, it's controlled strength in end range
- Sleep, walk, eat protein, the boring stuff wins every time
