New research reveals that if you want to tone up and slim down fast, you need to up the intensity of your workouts.
Intense, sweat-drenching workouts may be best to put your metabolism into overdrive for the next 14+ hours, according to a new groundbreaking study. In addition, other studies show that going at all-out or close to all-out efforts for short duration intervals improved aerobic capacity better than longer duration moderate intensity exercise–in half as much time! The evidence is overwhelming showing that high-intensity interval training (HIIT) is best to get fit fast and torch calories.
Like most of us, you’re probably workout out to help you lose lbs and firm up. Unfortunately, our wimpy ways of exercise these days just isn’t cutting it, says David Neiman, DrPh., Director of the Human Performance Lab at Appalachian State University, and one of the study authors. “We need to be pushed again to get lean with exercise. A 45-minute vigorous workout can help you get three times the net calories burned compared to a 45-minute walk.”
The study, published in the American College of Sports Medicine’s peer-reviewed journal, Medicine & Science in Sports & Exercise used a metabolic chamber (the gold standard for measuring energy expenditure) at the University of North Carolina. The researchers found that the men burned some 519 calories during the 45-minute exercise session and then burned another 190 calories from the exercise in the next 14+ hours.

If you completed a 45-minute walk, you’d burn about 250 calories and experience no increases above baseline in metabolism post-exercise. Spending your 45 minutes going harder can result in burning 3 times as many calories over a 24-hour period.
If you think you’re too out of shape for this type of workout, you’d be wrong. “We found that even the subjects who were overweight and out of shape reaped the same benefits. So unless your doctor says you cannot do vigorous exercise, this is something most people can do and could have an impact on achieving a healthier weight,” concluded Neiman. However, one thing that can undo all the good of this metabolic effect is if you think you can “reward” yourself with food after you’ve crushed your workouts. It’s too easy to eat hundreds of calories with just a few bites of something decadent so it’s always best to stick with your diet + intense exercise if you really want to see results.
The Best Exercise to Lose Lbs and Gain Muscle
There’s no free lunch when it comes to getting fit and lean. Do whatever exercise you like that you can really push yourself to the point where you’re seriously sweating and it’s impossible to carry on a conversation. Try boot-camp style workouts, Crossfit, a spin class or track workouts.
Run+ 10-Minute Workout
Run for a minute and at each minute, stop and do the following exercises, completing as many reps as possible in 1 minute:
Round 1: Push-Ups
Round 2: Sit-Ups
Round 3: Walking Lunges
Round 4: Air Squats
Round 5: Burpees
10-Minute X-Fit AMRAP (As Many Reps as Possible)
An AMRAP means complete as many rounds as possible in 10 minutes. Warm up for up to 5 minutes then go as hard as possible for as many rounds and reps as you can for 10 minutes. Repeat this workout every few weeks to see if you are getting through more rounds and reps in the 10 minutes:
The exercises are as follows:
10 Air Squats
15 Push Ups
20 Sit Ups
There are numerous websites devoted to CrossFit travel WODS (workouts of the day). These WODs generally require no special equipment and are usually anywhere from 5 to 15 minutes in length. They’re never boring and will be over before you know it.
A couple websites include:
