It could take you 2 1/2 months (shortest most dedicated time) but the most realistic would be if you decided to focus the next 4 months on changing your body into the ideal fitness shape for your body type. If you need any help let me know. I'm on the same journey But before you do you should research what your body type is (mesomorph, endomorph or ectomorph) and what the best type of exercises would be for that body type and then just plan your work-out routine. If you have any questions just ask. But I hope this helps!
