i have been having problems with my back lately.so i went to the docs and he says it could be the fact that im top heavy.i have newly discovered when i went bra shopping that my boobs went from a dd to an e cup.so doc tells me instead of doing cardio with high impact i should get an ecliptle trainer.so i was thinking a gazelle would be perfect.i have doing some research and found out there are different series of gazelles.does anyone have one or does anyone know wich one is the best?there are like 5 or 6 different kinds
