Session30 - 120 min

Surfing combines paddling endurance, balance, mobility, timing, and short high-effort rides. Much of the workout happens while paddling, positioning, and managing waves rather than during the ride itself. Conditions strongly affect intensity, so the same duration can feel easy one day and exhausting the next.

Training advice

Benefits

Surfing builds paddling endurance, shoulder capacity, timing, balance, mobility, and powerful short efforts. It also rewards reading conditions and staying calm in variable environments.

What to watch out for

Ocean conditions, collisions, wipeouts, shoulders, neck, and lower back need respect. Choose breaks that match your skill, know currents, and leave the water before fatigue compromises judgment.

MET (Metabolic Equivalent of Task) expresses how much energy an activity requires compared with rest. It is commonly used together with body weight and exercise duration to estimate calorie burn.
