hi friends i have never posted here before but /fit/ yelled at me when i asked for advice there so hopefully this is also okay
this picture is a few months old and the abs are the result of some really simple exercises i was doing most mornings (crunches, leg-lifts, and hollow-body holds, specifically) for like fifteen minutes or so. a lot of things have changed since then and i have lost all the muscle bc i lost my routine and got lazy, so i have to start over now.
anyways, i wanted to ask about what sorts of exercises i could do to get my whole body toned, like this. the routine i had was really simple and i actually had no idea how much of a difference it had really made until i realized all the muscle wasn't there anymore, so i'm thinking it does not need to be super complicated, but i don't know what exactly to do. what i had asked over there was if simply adding some push-ups and squats to the routine would suffice, or if there were better or more efficient exercises i could do. i have absolutely no idea what i am doing, so really any advice at all would be appreciated. ty :)
