How to Burn More Fat In Less Time

Many people point to a lack of time as the reason why they can't stick to a regular exercise routine. That's why books such as 8 Minutes in the Morning or The Slow Burn Fitness Revolution have become so popular. They promise to help you get in shape in less time and with less effort.

One simple way to cut down on the time you spend in the gym is to increase the density of your workout. Workout density is a measure of the amount of work performed in a specific time period. Don't worry if it sounds too complicated. Increasing workout density is actually quite easy when you use supersets.

Most weight-training routines require that you perform one set of a given exercise, rest for a minute or two, then return to the same exercise. And it's this rest period between sets that takes up a lot of time.

With supersets, you move quickly from one exercise to another, with little or no rest between. In other words, rather than resting between sets, you perform an exercise for another muscle group.

Depending on who you talk to, you might also hear supersets called compound sets or staggered sets. They're all variations on the same theme.

Supersets usually involve several sets of two exercises for opposing muscle groups, such as the biceps curl and triceps dip. A compound set is a superset for the same muscle group (such as two back-to-back exercises for your biceps).

With staggered sets, you do an exercise for one muscle group and then, with little or no rest, perform an exercise for a muscle group (usually a smaller one) in a different part of the body. As an example, you might alternate squats with dumbbell curls.

One of the main benefits of a weight-training routine that includes supersets is that it raises your metabolic rate in the hours after exercise. Studies also show a shift in substrate oxidation, which means that you're also burning more fat.

Some evidence for this comes from a study by researchers Kristin Osterberg and Christopher Melby [1]. A group of seven young women (aged 22-35 years), all of whom were physically active and lifted weights 3-4 times a week in addition to regular cardiovascular exercise, took part in the study.

They reported to the laboratory at Colorado State University early in the morning. At 1.30pm they began the workout, starting with 10-15 repetitions of the bench press. Without resting, they went straight to the bent over row. Each superset was followed by 2-3 minutes of rest. They repeated the process four more times, before moving to the next set of exercises. In total, the workout lasted 100 minutes.

The routine included several compound exercises, such as the bench press, bent-over row and overhead press. The women also trained hard, with the last two sets of each exercise taken to the point of muscular failure.

Measurements taken 16 hours later show the rate of fat burning had increased by over 50%. Resting metabolic rate was also up by about 4%. In other words, the women were burning more calories and more fat.

In a previous experiment from the same laboratory, in which men followed a similar program, resting metabolic rate was almost 10% higher the next morning [4]. When longer rest periods between sets were used (4 versus 3 minutes), the rise in metabolic rate after exercise was less pronounced (4.7%).

So, one of the ways to make sure your metabolism stays elevated after exercise is to keep your rest periods between sets relatively short.

The fact that the workout in this study lasted 100 minutes does limit the conclusions we can draw. Most people don't have the time or motivation to train for so long. However, at least one other trial shows a post-exercise rise in metabolism lasting for at least two days, despite the fact the workout took just 31 minutes [5].

If you find it hard to fit weight-training into your day, try increasing the density of your workout by using supersets or staggered sets. It's a very simple way to boost your metabolic rate and burn fat faster without spending longer in the gym.

Both the Maximum Muscle Plan and the Fight Fat and Win program incorporate supersets or staggered sets to help you make the most of the time you spend in the gym.
