@lostandfound123 If you have a spare 10 minutes, then use it to move.
For example, 10 minutes of kettlebell swings, either emom or amrap.
If you only have 5 minutes to spare, then use it to move.
For example, 5 minutes of shoulder presses, emom or amrap.
It kinda that simple, really.
If eventually you can commit to a routine, then you can transition to that, but if you don't have the time or energy, then make every spare minute count. The smaller workouts typically gather throughout the day, so eventually, you might have hit like 4 or 5 smaller workouts.
The main thing I'd say is pick a small amount of movements you want to get better at and focus more on them but obviously you can still stray away from that but it atleast creates a sort of routine without a routine as you're specifying the movements. You could even technically get a program with 5 movements and just break it up throughout the day whenever you have time.
As long as you eat, sleep, and move, you'll probably be fine.
