I am looking for a home strength routine which is more than just a list of exercises but also includes guidance about when and how much to increase my load. I know that there is a guidance of "Just increase the load once you get comfortable with it" but that does not work for me because I assume I am taking it too easy, increase the load too often, and end up with a lot of messy notes, workouts I cannot complete, and constantly thrashing back and forth between different levels.
I am fine with a fitness routine that is a document, like Couch to 5k or 100 Pushups or an app, assuming it is priced reasonably for my use case.
Desired level: I am not looking to get super buff, just enough to keep my muscles healthy
Duration: 30 minutes 2 or 3 times per week, so I can alternate it with cardo
Equipment I have: adjustable dumbbells and an adjustable bench
I see, like those push up progression plans. What are you training for?
Did you look into plans from e.g. jeff nippard? He's got some good plans. Like "The Body Building Transformation System (Intermediate-Advanced)". Maybe that suits you.
I would not leave reps on the table just because the program tells me to. Always do as much as you can. Go as heavy as possible while staying in the desired rep range for your working sets and keeping good form. I train for hypertrophy, training for general health as you write in the post, may be different.
Those push up progressions are not designed to get bigger muscles. Just to do more push ups. Like biking or jogging but with a different movement.
