I'm in the 3rd trimester and haven't been exercising much. I want to start now. I want an app I can use for the last couple of months and in the postpartum period, that will remind me to do 10-20 minute exercise routines & be safe to use after c section (eg focus on recovery initially). Any recommendations?? Finding it too hard to find time to swim / go to classes with a toddler and full time work and tiredness!
