Dad OS Weekly

Dad OS is a weekly fitness and wellbeing newsletter created by Jason for fathers over 40 who want to lose abdominal fat, build muscle, and feel less tired. Drawing on years of reading research and testing ideas on himself, Jason writes for busy dads with limited time—not gym enthusiasts seeking demanding programs. Each Tuesday, subscribers receive three practical moves in about 300 words, designed to take roughly two minutes to read.

The weekly format covers body, fuel, and mind: a manageable activity, a nutrition or supplement suggestion, and guidance on sleep, stress, or recovery. Advice emphasizes realistic habits, such as fitting exercise into a short schedule and choosing everyday foods, rather than complex protocols or intensive tracking. New subscribers also receive The Recomp Plate, a free, one-page guide to building meals for fat loss and muscle gain without weighing food or counting macros.
