Oh, Fresia, you made my day! I get to talk about running and how I started!
A member here (silent_tsol) had started running and I asked her what program she was using. She told me she was using the couch to 5K (C25K). It's a 9 week program with three workouts a week and builds you up slowly. You start the first week with a walk to warm up, then you alternate 60 seconds of running/jogging with 90 seconds of walking for a total of 20 minutes. By the end of week 9, you're running 30 minutes without stopping. A lot of people who do it take longer than nine weeks and just go back and repeat some workouts, and that's totally cool. The main point is that you get out the door.
Here's the website I used:
The Couch-to-5K ® Running Plan | C25K Mobile App
There is an app for your phone from that site, but it costs a couple bucks. If you have a smart phone, just search 'couch to 5K free' and something will come up to help you time your workouts.
Honestly, I thought running helped me so much with my mental health. Since I started running, I feel like I've been functioning like a normal person for once in my life. I made a social group for it so that people here at PC who do it would have a place to go for support and motivation. There's plenty of forums out there about C25K, but I figured, since we have the mental health aspect, it might feel safer and more comfortable for people to talk about it here. Someone once asked me why I started running and I didn't have an answer I felt comfortable telling this person. But anyways, our group has a whopping two members. I hope it'll get more lively
I hope your headache starts feeling better soon! And good luck to your dad and his surgery!
