Has the gentle rocking of the ship you were in ever interfered with your workout?
I'm a free weights and machines kind of person, I don't use Bosu balls... but are they used in ships? Will hilarity ensue? Pretty please?
And if the sea is nasty, will they close the gym?
But has anyone ever been affected by the rocking while at the gym? What happened? Are there specific safety measures at the gym? I suspect there isn't a squat rack, at most a smith machine, right? They wouldn't want anyone bending the bar in a ship... I think. Not that I do those... but would they allow Olympic lifting, for example?
So, in comparison to your local gym, how is the gym of a ship any different?
