Outdoor walk not counting as exercise -- not working for pregnant women

HI

I've using Apple Watch 7 to keep a record of my exercises etc.. however, sometimes my outdoor walks do not counted as exercise, which is very disappointing.

Understand that to be counted as exercise, the pace needs to be at 3.3 mph approx or above.

However, for many pregnancy women, this might be challenging to do so as women might suffer from pains like PGP or similar which stop them from walking at that pace.

It's not that fair that pregnant women try their best to keep up with exercise, but the efforts are not getting recognized.

Hope you can improve this.

Cheers.
