Congratulations! Appearantly talking excercise transition following parenthood here. Many interesting (and true) statements being made in this post.
Being 46 years old, having excercised regularly since age 16 (mostly bodybuilding), I have undergone two phases of de-mirroring, awarding me with more enjoyable results and self image.
First time was 10 years ago following a back injury, which made it counterproductive to lift weights. I then progressed to grouptraining two-three times weekly (bodypump type classes) for about 5 years, with the occasional gymsession as the body healed. Bodypump can be rewarding when building up to greater load being used, and allowing yourself a short break here and there during a song/musclegroup.
More recently (about a year ago) I wanted to return to a regular gym regimen, after some years of irregular training as a result of family life and work (responsibility that is). Firstly, I considered how much time I could allow for excercise? In my case, twice weekly on a regular basis. Secondly, I considered which type of training could provide me with as much result (strength/hypertrophy) as possible within that limited time frame?
My research brought me into HIT territory, starting out with Dr Ellington Darden’s book “The new High Intensity Training”. See his forum here on T-nation. My results speak for themselves. I am in almost as good shape as in my younger years of training - still progressing. Also, I spend 1/3 of the time I used to spend in the gym (for many years, using the regular High Volume Training approach) allowing me time for the other duties in life. You may try this approach for a couple of months, and decide for yourself if it’s a way to go - but in my case it answered many questions.
