I've hesitated about even trying a workout labeled "senior" as it seems it's always the equivalent of beginner/easy. Yes, it does appear that once one enters somewhere in the 50 to 60ish age group everything allegedly breaks down and falls apart all at once and 6 oz soup cans are the heaviest one can lift. I always smile to myself when our 35 year old daughter lets her ancient parents haul furniture up and down the stairs as she watches. She's thin but weak and seems to only care about what the scale shows and is worried that she will "bulk" if she lifts weights. But I digress.
Does it bother me that the fitness industry mostly ignores me? I guess not really, since I've always been unusually active for someone my age even when I was in my thirties. So I do the workouts that the younger people do and modify if I feel I need to, either up or down.
