If it's just a matter of time vs results, HIIT and overhead press/deadlift for 3 sets each of 5-10 reps, with ~2-3 minutes between sets (you can do stuff like bicep curls and chest flyes in between big exercise sets). Unpleasant but high reward/time.

If you want to optimize for exercise pleasantness, start consuming all your tv on a treadmill or elliptical at a slow-moderate (2.5-3m/h) pace.
