Exactly. I assume that your purpose is just to get the major muscles ready to go, get into the gym and build some muscle. You aren't a competitive golfer (yet) or sprinter (yet). Isolate the majors, work them, go home. That's why i really like the roman chair. It generally works a specific set of muscles in the lower back and butt (for instance the multifidus muscle) providing good functional strength for a lot of things later on, like squats.
