Loved gold's gym in venice beach, california. at 75, he still trains there almost every day and as i found out, he is all business. >> i get with the bike. i bike down. it gives me a nice warm up with a half hour ride and then i work out for around a half hour. i try to come every day. trying every day -- you end up like 320 days a year. it never stops. >> what's your work out? >> we work with a combination. i go with one machine to the other. sometimes it's just -- back day and then shoulders and arms and then abs and all of this. just like in the old days but with much less weight, less sets...
