Progressive
A lot of self-guided training never progresses. I start from your current ability and reassess it. That can mean a harder balance, more weight, a smaller piece of the movement, or more of the body in the same lift.
I strongly disliked fitness when I was younger. Long-distance running is what changed that. After a marathon I wanted something new, so I threw myself into strength training and building muscle.
Deadlifts and back squats stopped being enough. I still wanted to get stronger, and I wanted to feel I was learning. The training I do now puts balance and mobility inside the strength work. Muscles still grow. So does skill: arm balances, range of motion, control that was not there last month.
I keep it enjoyable. I work around what you like, what you avoid, and what hurts. Comfortable deadlifts in a busy gym are welcome. So is bodyweight work at home.
Training does not have to be an uncomfortable experience to be effective.
I coach at CityFitness on Newlands Road, and I write programs for people who train somewhere else.
