It's healthy, in that it's miles better than doing nothing. In really simple terms, anything that increases your heart rate that you can stick to 3+ times a week, every week will keep you physically fit. The limiting factor for most people is boredom. If walking, pushups, and sit ups is interesting enough for you then keep going. If you get bored, try running or adding some more exercises from /r/bodyweightfitness.
