I've been trying to make this point: Vacation time does not have to equal "weight gain". So stop fearing this notion. I'll share some tips including one of my many 3-minute workout routines.
This is why I've been posting (on my FaceBook page here) a bit of my vacation in Asia enjoying all the delicious foods, but at the same time, making conscious decisions with lighter foods and activities that can help offset all the extra calories--even without going to the gym.
I left on vacation and returned weighing the same. You may see a 2-4 lbs weight fluctuation throughout the same day depending on activities and consumption, (maybe 3-6 lbs for a bigger person), don't freak out, this is more than normal. This same-day weight fluctuation is not your true weight. Your "true weight" is your average weight first thing in the morning before you consume anything, providing you also didn't have a heavy meal the night before.
Also, you will not lose lean muscle mass in just 2-3 weeks if you choose to stay active and consume all your balanced nutrients: protein, carbs, good fats.
Furthermore, performing short, intense movements can be effective to set off your fat-burning mode especially during vacation, or right now when most of you are celebrating the holiday season with more than usual calorie consumption and less gym time.
With that all said, I'll share one of my "3-minute-a-day vacation (or holiday) fat-burn workout." In this short video I only show you a few repetitions of each exercise to keep the video short, but the actual repetition for each move goes like this:
10 burpees, 10 push-up, 10 burpees with push-ups, 20-30 spider climbers, 10 V-sit-up, 20 scissors with torso twist.
This should be done back-to-back with little to no rest. Repeat again if you wish to make it a longer workout, or just do it again later in the day if you feel like you need it.
For most of you, one set of this routine may take a little bit longer than 3 minutes to complete, but that is more than okay! Enjoy! :)
