I was actually on our college snowboard team all 4 years so I was thinking putting that as its own because of that so that and also mix that with skateboarding for the past 7 years. I did soccer for 14 years and play on our local team back home when Im there so I was thinking of mixing that and running to show they ere both ongoing varsity activities in college that I still partake in but at a much less serious level. And bodybuilding I may mix with yoga (took a yoga course one year and and practiced 2 years prior to keep myself injury free and help with flexibility). Sports have been a major role in my life but I also dont want to look like im trying to fill up space with it when I have stuff like clinical volunteering, research, and school groups. Idk if it will show that I was focused too much on hobbies+sports and not enough on clinical volunteering (cuz Ill have like 250-300 hours of that while having a ton if you count the multiple sports for multiple years).
EDIT: So for time breakdown I did cross-country/track since middle school. Varsity soccer+varsity cross country in the same season. Soccer for 14 years with playing on the state champ club team and regional runner up (decided to not play competitively in college). Ended school with 4 varsity letters in track, 4 in cross country+team captain+scholarship, 4 varsity letters in soccer, 4 academic letters. So lots of hours with those. Yoga for 3 years. Bodybuilding for 4 years. Skateboarding for 7 years. Snowboarding for 12 years+school team that competed in USASA competitions all 4 years. BUT the advice i was given was to condense all of this because it will make my app have a large emphasis on sports and to not have more than 1-2 hobbies in the activity section. Thinking that didnt really paint the full picture.
Sorry I misinterpreted the depth of the snowboard involvement.
I agree it's wise to condense some of the sport involvement so it won't overwhelm the typical premed ECs too much. You'll want to emphasize somewhere the aspects of sport involvement that translate well into being a good med school candidate: teamwork, dedication, working toward goals, etc. As well as how they played into your choice of medicine as a career (if they did) perhaps in the PS or where you have a Most Meaningful essay space to expand into.
For time breakdown, you might consider use of the Repeated feature to have several timeframes in the same space, like before HS, HS, and college years.
Keep in mind, you don't have to list everything. Emphasis should be on most recent sport involvement.
