Very cool! I like the simplicity of it. Right now I'm working on something similar for myself (and some of my family), but maybe other people find it potentially interesting too? Essentially I'm building a webapp that each time I use it will arrange random ~5-7 lower back exercises from a list of ~25 for a total of 10 minutes session. Then it will guide me (only time and name of exercise) through the workout session (counting down the exercise time, and pause/break time). The problem I'm solving is to not have to think too much about what exercise I should/want to do next, make it a little bit more fun/interesting (due to randomness aspect) and free my hands from operating a timer to time myself (also less likely to drift to social media or youtube videos). Thoguhts?

I had a spreadsheet set up much like that in the past: it would bubble up the exercises I'd done the longest ago for a particular muscle group so I'd always get variety. It worked pretty good, but I found myself often avoiding unpleasant exercises when given choices and eventually the whole arrangement fell apart due to too many moving pieces. I also didn't see the kind of extra benefit that I thought I'd gain from performing so many variations. I also used to set up fully scheduled on/off timers for specific exercises in an app, but found that any interruption would throw the whole thing off, annoying me to no end. However, your last point was also my biggest enemy. If I get distracted online for long enough to cool down to the point that I'm worried about injury, the whole session tends to just blow straight out. That's the main driver I had for putting the simple timer in the footer: keep my device on one screen from beginning to end!

I’ve also been toying with a timer based app that incorporates some randomness, which I feel is usually missing or poorly handled in fitness apps. Some random exercises and variable-range durations should improve motivation and give your body a better workout.

To quote Arnie: “You have to shock the muscle, and you have to trick the muscle. The body will adapt to anything you do, so you have to keep it guessing. That’s how you grow.”

I actually built something similar last week

I wanted something to create realistic yet slightly randomised warm ups and finishers - similar to CrossFit wods but more structured.

Behind the scenes I use a formula that estimates a total work capacity.

Feedback welcome!

I guess this should be easy to build on val.town or https://bolt.new/
