jtdashdub saidim starting back to the gym in about a months time and i was just wondering if i should go swimming after my workout?
I agree with paulflexes, swimming is not for bulking. Nevertheless it can be useful as part of a complete exercise program.
In the Army, I used to do gym workouts over lunch (very long lunches), alternating with days when I ran 2 miles on a woodland cross-country course. My goal wasn't bulking & brute strength, but meeting Army requirements for stamina, agility & speed. I generally did some swim laps next, which was both aerobic and also a kind of post-exercise stretching. And then I'd finish with a sit in the sauna, which further helped to avoid muscle soreness, to which I was prone.
Your regimen that you develop may be unique to you, and if bulking is your primary goal, swimming laps might be a good finish simply to retain flexibility. I would discuss this with a trainer, if one is available where you are. Swimming can help with toning and some sculpting, and cardio, but not bulking directly.
