CrossFit is a modern sport, introduced to the public in 2000 and popular quickly with more than 15,000 affiliates worldwide. Due to the highly demanding nature of the workouts, it is claimed to be a sport with a high prevalence of injuries. Most preliminary retrospective studies had shown that shoulder area is injured most frequently, at about a quarter of all injuries. Therefore, the initial goal of this observational (prospective cohort) study is to learn about the incidence rates of shoulder injuries and potential risk factors in a Greek population of CrossFit participants. Based on these results, this study's ultimate purpose is to create a short warm-up program capable of reducing shoulder injuries and evaluate its effectiveness. The main questions it aims to answer are: * Are shoulder injuries as frequent as previous studies have shown to be? * Can we blame for these injuries a previous history of musculoskeletal injury or deficits of range of motion, strength, and muscular endurance? * Can a short warm up which targets revealed deficiencies be effective in reducing shoulder injuries incidence rates? Participants will be asked to: * take part in baseline measurements (personal data, previous musculoskeletal history, shoulder and core range of motion, shoulder and hip muscle strength, shoulder stabilizers endurance, functional assessment sport-specific tests) * be monitored for new shoulder injuries or aggravation of old shoulder injuries that will occur during 12 months following baseline measurements. In this case, they must refer it to their coaches to be contacted and assessed by the researcher. * be in touch with the researcher throughout the observational study and provide any required data regarding their participation
