I’ve heard this called the ‘dirty 30’. It works. Whatever needs cleaning up or tidying, 30 minutes is just short enough to not feel like you’re using all your free time on chores, but long enough to make a real dent. Especially if your partner either helps with the same task or does a different one. Setting a timer can help and you start to almost frantically see how much you can get done. I like that competitive element even against myself.
Or see a physiotherapist instead.
