starting insanity again

So of course this year, I have started and stopped insanity twice. Now, I'm determined to start and finish. What I wanted to know from anyone who has done insanity did you still go to the gym also. I know that when Im done with a session of insanity. There is nothing left in the tank. I do have a gyme membership, but did not know if I should take a break from it those 60 days and just do insanity or both. Im all ears to suggestions or what you guys/gals have done.
Take care and good luck with all your weight loss goals and keep it up.
