Proactive suggestion
Suggestion 1
Every step should be 2-3 steps up as soon as possible. The whole process should be smooth and powerful, there is no requirement for speed, and you don't need to run very fast.
Recommendation 2
When climbing stairs, keep breathing evenly and smoothly. When climbing stairs, remember to touch the ground with your forefoot, just let your front foot step on the ground and your back foot hang in the air.
