Three months ago when I started at Horizon’s Gym I could barely do situps on a flat surface.
Each week, we’d move it up a bit or add some weight.
At my last session, the crunch board had been moved up for someone who was doing some serious work. I asked to leave it there. Why? ‘cos it was set to “11,” of course.
It hurt, but I managed.
Okay, doing situps at a steep angle isn’t a skill one needs to use frequently, but it’s still impressive.
