i find it harder to exercise on ss or ss+ just cause of the 2 main things you've said really. the energy i have is not there until i'm firmly into ketosis, plus if i go all out it lowers my losses. the 3rd is that initially it makes me hungry too.
i can do exercise if i lower the intensity as it doesn't really mess with my energy and losses. last night i took it easier but probably the intensity was still too high as when i got home i felt hungry (not straight after exercise though) so after my 4th cd i decided i need cottage cheese so i ate a tub. means my cal were higher yesterday but as it was all cd approved i feel ok about it.
the thing about zumba is i do go all out as i'm used to burning as many calories as i can so i look like a right loon. i lift my knees as high as i can, make my arms big, high etc, i move as far as i can across the room or forwards/backwards etc, i jump high, bounce etc i just make my movements extreme as it helps burn the cals. this week i'm not into the cal burn so i'm taking it easy, not wearing my polar watch and i'm not bothered how much or little i burn which is quite nice actually.
