The routines we actually use to keep riding hard in our 40s, written for any kiter. Short, practical, and each one links to the deep dive if you want the science.
The kite pulls your hips forward and tries to arch your lower back all session long. A core that resists that pull means a pain-free back, and strong legs mean knees that survive landings. About 15 minutes, 3 to 4 times a week.
| Exercise | Dose | Key cue |
|---|---|---|
| Front Plank | 3 x 30-60 s | Pull ribs toward hips, tailbone slightly tucked. No sagging. |
| Side Plank | 2 x 30 s / side | Straight line head to feet. Builds the side wall that resists kite pull. |
| Dead Bug | 2 x 10 / side | Lower back stays glued to the floor. Shorten the reach if it lifts. |
| Bird Dog | 2 x 8 / side | Hold 5 s, hips level, leg no higher than hip height. |
| Glute Bridge | 2 x 15 (or 10 single-leg) | Drive through heels, finish with the glutes, not the lower back. |
| Wall Sit + Block Squeeze | 2 x 45 s | Squeeze a yoga block between the knees for knee tracking. |
| Pull-ups or Rows | 3 sets, 2 short of failure | Lats and grip for bar control and unhooked riding. |
| Push-ups | 2-3 sets | Balanced, stable shoulders for crashes and water restarts. |

Tight hips and backs after riding are mostly your nervous system guarding the joints, not short muscles. Forcing a deep stretch makes it guard harder. The fix is a sequence: calm it, center the joint, open it up, then lock the range in with strength.

No extreme diets. Real food, enough protein, a daily eating window, and the occasional longer fast when the wind is off.

Sleep is when your body actually repairs the damage from the session. It's the most powerful recovery tool you have, and it's free.

Most serious kiting injuries happen on land, during launching and landing, or from gear failure. Five minutes of prep removes most of that risk.

A tense mind makes a stiff body, and a stiff body crashes harder. The riders who progress fastest aren't fearless. They know how to calm down, commit, and keep it fun.

Riding for decades is a long game. The right goals, the right people and the right attitude keep you improving and keep you loving it.
