Set your feet as though standing on two parallel tracks, with one foot ahead of the other. That is a more workable starting idea for a split squat than balancing both feet on a tightrope. The feet stay in place as you bend and straighten your legs.
Stand beside a fixed rail or another genuinely stable support. Use it lightly for balance, and begin without added weight. Find a distance between the feet that allows a small, comfortable lowering movement. The rear heel will usually be raised, while the front foot remains securely on the floor.
The first attempt need not be deep. Lower a short distance, return to standing and check whether you can repeat the same path. If the stance feels cramped, reposition between repetitions. If it feels so long that you are being pulled apart, shorten it. The arrangement should allow controlled movement, not enforce an impressive-looking stretch.
Give each side its own setup
Switching legs is more than spinning around quickly. Reset the feet and handhold, then take a moment to find your balance. It is common for the two sides to feel different. Use a range and effort you can control on each side rather than forcing the less comfortable side to copy a depth it cannot currently manage.
A light hand on the support does not cancel the leg work. It reduces the balance demand, which may be precisely why you chose this version. Avoid pulling yourself up forcefully with the arm unless that assistance is part of an individually planned adaptation. If your arm is doing most of the movement, reduce the depth or seek help with the setup.
This is a stationary split squat, not a rear-foot-elevated variation. There is no need to put the back foot onto a bench to make the exercise legitimate. That change creates additional positioning demands and may be unnecessary for your goal.
Keep the surrounding floor clear, especially behind the rear foot. Loose bands, towels and nearby weights become harder to see once you are concentrating on a split stance. Stop if the movement produces pain rather than ordinary effort, and get advice about persistent symptoms.
When you can repeat several comfortable repetitions, decide whether you need a change at all. You might practice a slightly greater range, use less hand pressure or eventually introduce an appropriate light load. Change one thing, with the support still available, so that confidence develops alongside the challenge.
