I can share what I did because I recently went through this journey. I started with Pavel Tsatsouline's Simple and Sinister program and bought a few kettlebells. I slowly started to incorporate push ups, overhead press, curls, dips, squats, deadlifts all from home - with apartment friendly and novice modifications. I then bought some exercise bands and learned some more exercises from youtube. The best advice I read was to start small, make it a regular thing and go from there. Like seriously, I started only working out 15-20min each session 4-5 days a week for the first 2-3 weeks. I enjoyed it so much and saw great results that now I'm at 45-50min minutes each session a few months in.
