2026-05-25, 82kg, Apple Watch Ultra HR 158 avg. My reference for kettlebell swings is 640 kcal per hour. 28°C indoors, 4:40pm at Tsuen Wan Gym. My grip gave out before my legs did.
MET 7.4 is the approximate equivalent of my 82kg rate, not a separate measurement. My 82kg reference is 640 kcal/hour. At 70kg, that's about 546. At 98kg, about 765. The formula (minutes × MET × 3.5 × kg) / 200 is reference only. USDA FoodData is used for food cost, not exercise burn.
What could 30 min cover? About 320 kcal, close to Takoyaki 6pc (320 kcal). I'd treat that as a comparison, not a reason to earn a meal.
