I usually just get my bike workouts in after work. Takes about 1.5-2.5 hours right after work, full effort intervals or time trial work during the week, long rides (4+ hours) on the weekends after I'm done brewing. Don't do a whole lot of gym work anymore, just bike specific stuff.
BTW, I'm your stereotypical skinny cyclist. 6' 135 lbs, huge legs with skinny arms, eats like a sumo wrestler.
