Moderator's Edit from 2/8/2022 to add additional information provided by original poster via email:
Chainsawing wood is exerting energy and burning calories as so is the splitting of the wood by hand with a splitting maul. You work up a sweat even in our cold Wisconsin Winter's. At 67 years old it keeps me in shape. 5' 9" and 160# pounds of dynamite. If you don't believe me try it for a day. We love using Strava for kayaking, walking, snowshoeing, biking and soon to keep track of my wood splitting and chainsawing. Thanks, David J.
