The winter workouts are really great for the team to build strength before the season starts. Not only does it help with injury prevention, but it gives us all time to bond after school to clear our heads and train as a team.

The MKA weight room has significantly increased my performance on the athletic field and has assisted me in reaching my athletic goals. The trainers are always present to assist anyone with injuries and help them get back on the field as soon as possible. The weight room and trainers are the backbone of our athletic department, and all the athletes are thankful for their presence. The school has given athletes the opportunity to enhance their performance by keeping the weight room open daily from 3:30 to 5:00 p.m. The weight room and training room have all the equipment I need to succeed as an athlete. The football team and all other teams are very thankful for it.
