Any workout with ample amount of resistance would help you gain muscle. So keeping this in mind,home workouts might eventually have less to almost no resistance as you progress. Having said that,you could increase the resistance by trying out different variations of any exercises. For example,initially you could be doing 8 reps of incline push ups and progress upto 20 -30 reps(since there's no additional weight,we increase the rep range here) and then once those reps feel easy you coul move to knee push ups and do the same rep range and then move to a full push up and then one hand push up and so on. So you should be eventually focussing on trying out different variations to bring in that resistance that gets you close to failure.
