For something like Cancun, which is in 2 months, you should focus on that cardio and drop a few lbs. In a perfect world, if you had more time to work with, I would say to bulk up before cutting down. The reason being that you need a lot of muscle before cutting so you'll be able to SHOWCASE your muscle hidden under the fat.
My suggestion is to hit up three heavy days a week for weight training, and cardio in between. You're going to be doing a lot of walking around on the beach, so it makes more sense for you to drop a few pounds and hit up the tanning booth.
Fat loss is FAST, muscle gain is SLOW. Take the fastest path to hitting up some latinas IMO. Benefits of cardio:
- Increased alcohol tolerancy
- You'll appear to look healthier
- More energy/stamina
- Lowerered need for food
^^ That to me is what you're looking for in some place like Cancun.
No woman turns me on more than a hot little Mexican!! I hope you're not married!
