I would drop arm work outs and do body weight squats and pushups (do them on a step if you can't them horizontal yet). I would do them back to back for 4 or 5 circuits. Do a set of body weight squats, catch your breath and do a set of push ups. Catch your breath, do another set of body weight squats, catch your breath and do another set of push ups. Do 4 or 5 rounds. Finish it off with some stretching/mobility. Push ups will work your arms.

I got a bodi membership and am doing “for every body.” 20-25 minute videos 4 days/week. Low impact and no fancy moves, but effective in targeting all body parts, mobility etc.

I also likes “muscle burns fat” on bodi, but it’s harder.

A stretching class like Yoga wouldn't be a bad add.

mobility work

Core. Pilates or yoga, sit ups, planks, etc.

Slow, steady progression is the way to go. Add some basic bodyweight strength exercises, such as air squats and pushups

I hate working out, but I’m in my 40s and know I need a sustainable routine that I don’t hate.

Over the course of the last year I’ve been slowly ramping up, adding one piece at a time until it felt routine.

So far I get 10k steps daily, one mile on the treadmill daily, and a 10 minute arm video at least 3x a week.

I’m ready to add another component. Maybe more strength to alternate days with the arm video? What am I missing that is a must? Legs? Core? Again, I’m just looking for baby steps here - otherwise I won’t stick with it.
