Yeah, so add stretching/yoga a bit beforehand, add in some reps of crunches/situps/squats, do an hour routine like that that 2 or 3 times a week, go for a 30 minute walk/jog/run on off days.

Its… really not that hard or complicated for a person who is already in reasonabley ok health to put together a simple workout routine, that will hit most of your muscle groups, get you into decent shape.

Hell, just going for a 20 minute walk 3 times a week is I think more excercise than half adult Americans get, and that’s actually significantly better than nothing.

Get some stretchy bands, do resistance training positions.

Fill up some empty milk jugs with water, do some curls.

Pretty much the only thing I think you might actually need would be a solid pullup bar, but if you’re doing pushups correctly, maybe not.

Or, you could just find a place to go swimming.

Easier to get into for people who are in less good of shape, and basically works every single muscle group, if you have do a variety of strokes.

Theres ‘getting into decent shape’ and then there is ‘bodybuilding’/‘sport-specific athletic training’.

Its not very difficult or money intensive to ‘get into decent shape’, so long as you don’t have serious pre-existing health issues.
