Did you start exercising together while working out as a maunza?

I'm thinking of doing some workouts along with the Mounter, but I'm worried that if I do both intensely from the start, I'll get exhausted quickly.
I usually don't move around much, so I'm thinking of starting with walking.

For those of you who just started, did you adapt to diet control first before adding exercise?
Or I am curious if it would have actually been easier to form the habit by doing it together from the beginning.
