An intricate part of the dicussion deals with folks who do not care. When I used firewood, I also ignored the cost. It is a homeowner's right.

However, disagree that a seasonal activity results in year around fitness. The opposite is likely true. Inactivity in winter and spring, coupled with sudden strenuous activity in summer, is likely to produce physical stress , strain or worse.

Choose wheelbarrow over bucket. Sure, even with tools, work is involved. But selling it as the same as routine and balanced, consistant exercise is a stretch, and stretch exercises are different! The solitude of woods work and communing with nature is healthy, even fun, enjoyable, just not most recommended form of exercise.
