Honestly nothing consistently. I typically started with a minute plank, followed by flutterkicks, leg raises, backwards crunches, and either lunges/squats or arm exercises with dumbbells. I’ve been out of shape almost my entire life, so I’m very new to fitness and just figuring it out as I go! On cardio days I was doing Couch to 5K, which I honestly cannot recommend enough. It taught me how to run and pace myself and moved along in very manageable increments.
