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


You’re looking for Easy Strength. Follow the set and rep scheme. Never miss a lift - never even come close. Pick lifts that work with the equipment you have, and change things up every few weeks. Workouts can last just 30 min. Finish the workout feeling fresher and more energized than you started.
I recommend getting a door frame pull up bar, some elastic bands you can use to take weight off pull ups, a device for hanging weight from yourself to add weight to pull ups, and an ab wheel. This prob won’t set you back more than $40, even buying new.
Otherwise, you can look into tons of other classic lifting programs like starting strength, strong lifts, greyskull LP, etc - but these typically assume access to a barbell.
But honestly my best suggestion is to get into some sort of strength-based social activity. Join a gym/club for powerlifting, strongman, oly lifting, highland games, wrestling/martial arts, rock climbing, parquor/ninja warrior, acrobatics/acroyoga, aerial arts, gymnastics/calisthenics, landscaping/construction, the field part of track and field, crossfit/bootcamp/group fitness classes, obstacle course races, etc. The workout that works best is the one you stick with, and the one you stick with will be fun and friendly.
