Welcome to CrossFit @tkki. Glad you like it so far. I’ve been doing it for 7 years, my advice is don’t try to do a movement or lift an amount of weight just because others at your box dot, or you will increase risk of injury. If you are smart, it is very safe.
Wow.. 7 years! I really appreciate for your kind advice. Won't compare other's record, but will focus on my status. Thank you.
