Exercise DOES Work: Combat Holiday Overeating with Intense Exercise

by Tim Skwiat, MEd, CSCS, Pn1

We are now deep in the heart of the holiday season. You likely feel like you’re running around like a chicken with its head cut off. As a matter of fact, you may be so stretched for time that your workouts have taken a backseat. Being strapped for time can also mean compromising your nutrition. What’s more, we all know that this time of year is the epitome of holiday parties, which means overeating less than optimal food choices.

That’s right, the holiday season is the hallmark of moving less and eating more, which can be a catastrophe for your body composition, health, and vitality. Chronic overeating, also known as a caloric surplus or a positive energy balance, can have major repercussions. While most of us think about the obvious weight gain, there are other factors to consider: overall health, cellular fitness, blood pressure, cholesterol, insulin resistance, risk for certain types of cancer, and many more.

While there many ways to avert these potential pitfalls and avoid becoming subject to this self-fulfilling prophesy, you may not have to become a recluse and steer clear of all the wonderful holiday goodies. New, appropriately-timed research suggests that keeping up with your daily workouts counteracts the negative metabolic effects of short-term overfeeding.

Researchers from the University of Bath in England recruited 26 healthy young men between the ages of 18 and 32. The lads were separated into two groups, one of which was an exercise group that performed 45 minutes of treadmill running at a moderate intensity (e.g., 70% VO2max) daily. The other group did no exercise.

Both groups were charged with the responsibility of significantly overeating. The non-exercise group was instructed to consume 50% more calories than their habitual intake. In order to ensure a consistent energy surplus (not to be canceled out by exercise energy expenditure), the exercise group consumed nearly 75% more calories than normal. Now that’s some serious overeating, and this went on for a full seven days!

In addition to the overeating, the researchers had both groups significantly reduce physical activity. Both groups were instructed to wear pedometers as a gauge of their activity, and the scientists had all participants reduce their steps from 10,000 daily (pre-study) to less than 4,000 per day (during the study). Besides running on the treadmill, the exercise group was forced to be just as lazy as the non-exercise group.

The duration of this experiment was one week. Both prior to commencing the study and after the 7-day period, the researchers collected various health measurements, including fasting blood sugar and insulin and biopsies of fat cells.

The results, in just one short week, were staggering. The non-exercising group displayed worrisome changes in fasting blood sugar and insulin levels. What’s more, their fat cells demonstrated health-derailing changes in the expression of key genes, which were a sign of much-maligned changes in metabolic functioning.

The exercise group, on the other hand, was not similar afflicted. As a matter of fact, the scientists concluded, “Vigorous-intensity exercise counteracted most of the effects from short-term overfeeding and under-activity at the whole-body level and in adipose tissue, even in the face of a standardised energy surplus.” The effect was so profound, that the authors of this study titled it “Exercise counteracts the effects of short-term overfeeding and reduced physical activity independent of energy imbalance in healthy young men.”

What does all of this mean for you? Simply put, you can offset the cascade of negative health effects that accompany overeating and less than stellar nutrition habits during the holiday season by making time for a vigorous daily workout.

As mentioned at the onset of this article, time is precious. What’s more, 45 minutes on the treadmill does not sound at all enticing, and you may not have that much time to spare. On top of that, it’s plausible that exercising at an even higher intensity and including some resistance training can provide further metabolic benefits. Heck, you may even be able to add some lean muscle mass if you play your cards right.

The solution: Barbell complexes. These efficient but nasty combinations pack as much bang for your buck as pretty much any routine you’ll find. What they lack in time and equipment, they more than make up for in intensity and metabolic demand.

The name of the game with complexes is to choose a series of exercises that can all be completed with the same barbell (or set of dumbbells). You take minimal rest between exercises and a short rest between sets, or rounds.

One of the more frequently asked questions when implementing complexes is the amount of weight to use. Generally speaking, the load is going to be pretty conservative. As a matter of fact, you might find that the barbell by itself provides enough of a metabolic stimulus. Muscular failure is not necessarily the goal, although you may base the weight on your weakest movement in one of the complexes. However, if you’re not questioning why you’re doing these halfway through—or earlier—then you’re probably not going heavy enough.

Each of these complexes will take only about 15 – 20 minutes to complete, and very little equipment will be needed. [Note: Please do a proper, thorough warm-up prior to commencing one of these routines.] You’ll simply choose one of these complexes and utilize the following guidelines for sets, reps, and rest:

• Beginner: 4 sets of 5 reps each exercise; rest for 90 seconds between sets.
• Intermediate: 5 sets of 5 reps each; rest for 75 seconds between sets.
• Advanced: 5 sets of 6 reps each; rest for 60 seconds between sets.
• Sadistic: 6 sets of 6 reps each; rest for 45 seconds between sets.

Generally speaking, each complex will contain some combination of the following:

• Explosive movement
• Lower body movement
• Upper body movement (push)
• Lower body movement
• Upper body movement (push)
• Miscellaneous

Without further ado, let’s get to the chaos!

Complex A:

• Hang Clean + Front Squat + Overhead Press
• Reverse Lunges
• Bent-over Barbell Row (overhand grip)
• Jump squats (no barbell)

Complex B:

• Hang Snatch
• Romanian Deadlifts
• Push Press
• Back Squat
• Upright Row
• Bar Rollouts

Complex C:

• Split Jerk
• Deadlifts
• Back Squat
• Lateral Lunges
• Bent-over Barbell Row (underhand grip)
• Lunge Jumps (no barbell)

Complex D:

• Squat Jumps (with barbell)
• Front Squat + Overhead Press
• Step Ups
• High Pull
• Burpees

You’ll simply choose one of the previous complexes and the appropriate set, rep, and rest guidelines shared above. You can incorporate these complexes as a workout themselves when you’re strapped for time. You can use them as a form of metabolic conditioning separate from your strength training workouts. Or, if you’re especially sadistic, you can use them at the start of your regular workout. You’ll just want to complete them when you’re fresh.

Just remember, these are not for the faint of heart. They are very challenging, albeit incredibly time-efficient. Not only will they offset any holiday overfeeding, you’ll actually find yourself in significantly better metabolic condition, and you may even drop some fat while you’re at it!
