First year mainly wrist and as I was progressing with smashes I got kind of an shoulder impingement. But this was through pushing Padel a lot and playing way more often than my body was capable of.
Now in my second year I am also fighting a lot with my hips, lower back and now also a bit with my knees. I am playing around 4-5x each 2-3 hours each which is probably a too fast increase for my body. So finally I decided to take action and go additionally to the gym and stretch. After the gym I feel a huge relieve in my whole lower body. Also I just train lower body in the gym. In the future I will probably also do upper body. But for the next half of a year I decided to just concentrate on my problem areas.
I also found out that it's really helpful to stretch some parts after the padel games. I stretch the neck, breast, calves, quad, hip flexors.
I think a lot of problems I'm facing are coming from my sitting job + sitting aside from the job a lot. So I also see a lot of progress by correcting my sitting position (I was definitely not sitting healthy by pushing my shoulders in front to the keyboard and rounding my back) and switchting between sitting and standing. And to be honest I also thinking of creating a small workplace on the ground so I can sit on the ground and very there a lot more with more healthy sitting positions - I am obviously working from home office because otherwise this probably would be pretty much weird.
