Thank you!
You might know that I had bad back issue around last Christmas and this January so that I bought several strengthening work out video etc. on 7/3 and 7/4 this year, I had worst lower back pain. I took ibuprofen 800, which usually help relieve pain, did nothing and I could not walk for few days. I went to orthopedic walk-in to get it checked. X-ray showed that my L5 lumber vertebra bone got pushed back and got out of position. It was really pushed out enough so that doctor did not tell me which bone got pushed back out of vertebral column.
I was watching Petra Martic and Iga swiatek’s Wimbledon match about a week ago and I remember commentator said that Martic had one year off because of back injury. Her serve looked somewhat different in a way that her back was fairly straight and not much shoulder over shoulder type of tilt. I am thinking that I want to model her serve for my back issue. If you happen to know good way to serve for someone who has back issue, please let me know. Meanwhile, I started to resume my core exercises, which I was getting lazy and started to skip recently.
Thank you so much for reply
