Getting 1% better results for the average person is going to be nullified by the beers they drink on the weekend/the multiple days they skip because they dont feel like working out/any number of other normal life actives that are not optimal.
Find a way to exercise that you enjoy it and do it often. After that don't think about it too much.
Recently I've been riding an exercise bike after work while playing a video game on my computer with an xbox controller. Every 5 minutes I hop off the bike and do some weight training then get back on the bike. I ride for an hour. Doing this most weekdays has lead to far better results than when I used to go to the gym because I actually do it everyday/most days and I don't rdread it.
