Can I do abdominal exercises in bed?
I really want to strengthen my abs. Can I do ab workouts in bed where the cushioning is much better than on the ground? Will this make my exercises less effective? They sort of feel less effective because I get little resistance from my bed. Please help!

Is this a trick question?
Yes, doing sit ups and crunches in bed is very good because the mattress will contour to your back….sex is a great exercise too.
