I rowed Men's lightweight crew for a little while. It is possible to be involved in club activities while doing crew, but it is extremely difficult to do so. Crew practice usually goes from 3:30 6-6:30 and dinner from from 6:30-7.Every club meeting is from 7-8. You are looking at starting your homework after 8:00 with club meetings and practice. Don't forget to count that you will be exhausted by that time and you have to be in bed by 11 o 'clock. I have seen few people balance a varsity sport and a club, but it is definitely not common. I did zero clubs when I rowed. Now I am active in four clubs. Food for thought
