Hey! There is not really a difference. Transition is just meaning time to the next workout. But you use this time for resting 😉

such a typical Rappa reply lol, ok, transistion means you are changing your stance, position, change of equipment, from floor to bench, standing to lying, etc.. rest is recovery. 

Hi,

I have a question. I have heavier and more frequent periods since I started consistent exercising. Is it normal? Anything to be concerned of? Does it mean im not doing exercise right? Can it cause infertility?

Any idea as to why i feel extremely dizzy and nauseous after crunches? Anything to do about it?
Or are there any other exercise to do to work on muscles instead of crunches?
