I know it's super late in the year, but do y'all mind if I jump in? I had a baby in November and am working on getting back into my old stuff. I was doing competitive powerlifting before I got pregnant, training in Aikido a couple of times a week, doing long bike rides (as well as commuting by bike), running some (did a marathon back in 2012 but only short distances since then, and no races), and had very good intentions of getting back into yoga, which I've been practicing on and off since I was 18. As you can see, I like a lot of variety in my fitness!
During pregnancy, I did Aikido till 35 weeks, and kept cycling to work till 37 weeks, but that was it.
Currently, I'm doing a little of everything. Powerlifting is my main focus & priority; I'm doing the Starting Strength novice routine 3x/week. I'm up to 135x3x5 for squats, 70x3x5 for bench press, and 165x1x5 for deadlift. I'm going to test 1RM's in a couple of weeks. I'm really excited to do that; I've been making gainz WAY faster than I expected. Pre-baby, my 1RM's were 200, 110, and 240. I think I can surpass those by the end of the year, and that's my goal.
Also running, 2-3x/week. The longest I've done is 2.25 miles so far. I'm going to do a half-marathon with a friend in November.
Cycling: mostly to & from work (only 4.25 miles each way, sadly), plus Spin class at least once a week. I really want to do a ride with my local cycling club, but I haven't been able to get out because of my and my husband's schedules. Soon, I hope! I also have tentative plans to get certified as a Spinning instructor later this year, and make a side hustle of it.
Yoga: been doing about 2 classes a week at the gym, and occasionally a DVD at home. My gym just hired 2 new instructors, and I really like them both. It's nice to be back into this, and the stretching is a good counter to so much lifting.
Aikido: I've only been to 1 class so far this year. :( Again, it's an issue of scheduling. I can only go when my husband and I are both off work, because I can't exactly take the baby with me, and I don't want to pay a sitter.
Oh, yeah, and I'm hoping I'll lose some weight in all this. Pre-pregnancy, I was around 150. Highest after pregnancy was 175. I'm currently at 169 and hoping to get down to 125ish by the end of the year (I'm 5'3").
