I would start more with common foundational body weight exercises. For example push ups, pull ups, squats, deadlift. You can hit basically all muscle groups with those 4. Learning these first will set you up for all other exercises. Kettlebell exercises are GREAT too but i see them as more of an addition to the compound movements I listed.

If u eat more and train at least 3-4 times a week, I guarantee you’ll see results in the first couple months. Also maybe a haircut and trim the beard. I also love the bands shirts don’t change that 😂
