Can you achieve peak physical fitness through indoor and home workouts?

Let's admit it, while we all want to go to the gym, not everyone can at the end of the day due to either the cost of going to the gym or personal schedule. With the rise of high-quality fitness apps both paid and free,compact home gym gear, and routines like indoor jogging or bodyweight calisthenics, these days most people prefer working out at home rather than going to the gym. Do you think it's possible to gain peak physical fitness from just home workouts?
