Vyayama — Exercise as a Daily Health Practice
Vyayama (physical exercise) is prescribed daily in Ayurvedic Dinacharya at half-capacity — never to exhaustion — as a key practice for Agni stimulation, Kapha reduction, strength building, and mental clarity.
Vyayama (from 'vi' + 'ayama' — exertion, expansion) is recommended daily in classical Ayurvedic texts, with a specific qualification: Ardhashakti (half one's capacity). Charaka Samhita defines the optimal exercise intensity as when slight sweating appears on the forehead and nose, the breath becomes slightly elevated, and the heart rate is elevated but comfortable — what modern exercise science would recognize as the moderate aerobic zone. Exercising at full or near-full capacity regularly depletes Ojas, aggravates Vata, and accelerates aging; exercising at half-capacity consistently over time builds Ojas, reduces Kapha, strengthens Agni, and produces the 'lightness, ability to work, firmness, tolerance of hardship, diminution of impurities, and stimulation of digestive fire' that Vagbhata lists as benefits. The ideal time for Vyayama is Kapha time (morning, before 10am) when Kapha's natural heaviness can be metabolically utilized.
Exercise at half one's capacity produces lightness, ability to work, firmness, tolerance of hardship, and stimulation of digestive fire.
Research on moderate versus high-intensity exercise and all-cause mortality (Lee, 2014, Journal of the American College of Cardiology) found that moderate runners (the Ayurvedic 'half-capacity' recommendation) had the best longevity outcomes — lower than both sedentary individuals AND strenuous exercisers — validating Ayurveda's counterintuitive recommendation for moderation.

- What Ayurveda says about rest
The classical exercise dose is Ardhashakti, half your capacity, stopping when sweat appears on the forehead and nose. Going to the limit habitually is said to deplete Ojas, aggravate Vata and accelerate aging. Rest, on this reading, is mostly built into the work rather than taken afterwards.
