I'm currently doing rowing for my physical, and its my 6 month thing. the issue is, I know it's 1 hour a week, however my club takes breaks for christmas and other holidays. therefore, i can't row during the holidays, and cannot do the 1 hour a week. im planning to do 3-4 hours (the most I can do in a week) from when it restarts in January, but still what can I do about the breaks/holidays? Is it possible for me to catch up?
