No shit you saw no results - that is a SILLY amount of cardio.
Step Aerobics - 3 hrs/wk
TaeBo - 1 hr/wk
Running - about 6 hrs/wk total (?)
Elliptical - 1.5 hrs/wk
TOTAL - about 11-12 hours a week of cardio
And I am betting you did it 7 days a week, huh?
Plus, some weight training - although, time is mostly irrelevant unless intensity/exercises are known. PLUS, a low cal diet and likely not the best food choices....
Holy Cow!
I am glad you are here and changing your training!
