The think it depends on the individual. I used to utilize this site for various reasons. https://nowloss.com/
It is best to use a computer for the site. (it needs some work or an upgrade) I doubt all of it shows up on a phone. I came across it yearssssssssssss ago when I was looking for posture improvement things and hit the mother load.
I'm not too serious and almost lazy with strength workouts. I try to save as much time as possible. My workouts could be considered laughably small, stupid, ridiculous. But old friends have told me they noticed that I've worked out. Looking back at old photos, I notice it even more.
I have a heavy bag (10-15kg) that I take to work (filled with electronic devices, batteries, water bottles etc). I lift it in various ways (arms, shoulders, squats) whilst I walk to work. (so I don't dedicate additional time in the gym to save time.) I do only 15-20 reps 1 set or sometimes 2 set. Not even consistent. I'm not even serious about making big gains. If I was serious, I'd be doing more than 1 set per day.
I start of with 1-3 sets of pushups in the early morning after a run. I notice a difference in 3 months.
Pretty much doing anything at all will produce any gains. And again, I don't do so much that it hurts the next day. Consistency and regularity is the main thing for me. Then I do it and forget about achieving any goals. The gains come gradually on its own.
