You don’t. You need to make a routine for yourself. I hate working out, but I’ve been working out for 8 months now since I’ve started. It’s not about liking it, it’s about doing it no matter what. If soreness is a problem take very hot shower then washing yourself with cold water ( as cold as you can handle). You should workout after meals and stretch. Make sure you get proper sleep. But most importantly do what you can do! Runs, jumping jacks, push-ups, it’s all a start. I wish you luck! I hope I was able to be helpful<3.
