*Excellent*.
But go *slow* in the beginning.
I know you probably already know that, too; still, just cannot emphasize that one point, enough.
One other thing.
If you've got a basement -- & assuming you haven't already done this -- consider buying a few pieces of gym equipment for your *own* gym.
Nothing "expensive" is called for here.
A decent bench, long bars & casts, dumbells, maybe an "good" Schwinn Aerodyne?
All of which can be had for firesale $$s from the want ads.
You & your bride (*after* you've fed the babies) could go downstairs & do your routines after dinner clean-up's finished, when YOU want to without driving "to" anywhere, being distracted (by you-know-what) or having to wait for machines.
I cannot possibly stress the mulitiple benefits of doing something like this with your lover as you get the rare chance of participating & then watching the results appear before your eyes, together, & under your own terms.
Plus consider this: many opportunities for shenanigans & hyjinks of all manner just seem to just *pop-up* during these kinds of private exersize sessions, eh? :o)
(~a "hidden" fringe benny for us guys, if you please?)
Kids are always just a hollar away upstairs, & safe, too.
~eh?
Anyway, just my .02 suggestion as we've done this for years and I speak from experience.
...can never get too close to your partner, partner. :^)
