what should i do if i dont have a moon board or tension board?
If you don't have a Moon Board or Tension Board, focus on improving your climbing technique and overall strength. Practice precise footwork, body positioning, and efficient movement on different climbing routes. Incorporate exercises that target your core and antagonistic muscles to enhance your climbing abilities. Additionally, consider exploring other climbing gyms or outdoor climbing areas to challenge yourself on various routes.
Try to find the next best thing that you do have. Do you have a spray wall? If not, do you have an overhanging wall that you can make up boulders on using the existing holds?
Otherwise, I would just make up boulders anywhere in the gym and try to make them system-board-like.
