Not that I know of. Bit, be aware, sparks uses more than just inputting an activity. It takes your information I. Your profiles, sex, height, weight, etc., so make sure those are accurate. It's still just a guesstimate. If you re worriednitsmwildly inaccurate, I'd suggest investing in a HR monitor. You fight also double check it against another site like caloriesperhour.com and use the average, I've done that before. When I do the elliptical, I use the average of the machine and SP since the machine is always super high, and I weigh less than the average most machines are calibrated for, but SP doesn't take intensity or incline into account.
I am 5'4".
