First of all, know that hitting a plateau is completely normal. It happens to everyone, and it does not mean you are doing something wrong. It is actually a sign that your body has adapted to your current training load, which means the training is working.
Before you change anything about your training, look at the basics. How is your sleep? How is your nutrition? These two factors are responsible for more stalled progress than any training mistake. If you are sleeping less than 7 hours consistently or eating too little protein, no program adjustment will fix that. Start there.
Next, are you following your program exactly as written? Many people unknowingly skip deloads, add extra sessions, or swap exercises. Deload weeks feel like a step back, but they are where a lot of the adaptation actually happens. If you have been skipping them, schedule the next one and follow through.
Also check your form. Progress on calisthenics is tightly linked to movement quality. Sometimes what feels like a strength plateau is actually a technique issue that is limiting how much muscle you can recruit. Record yourself from the side and compare to what a clean rep looks like.
Remember that progress is not always visible. Strength is building under the surface before it shows up as a new rep or a harder variation. Trust the process and give it time. If you have been following the program consistently for more than 8 weeks with no change at all, reach out to a coach. We will look at your specific situation and figure out what is going on together.
