Eliminate Boredom. People tend to start with all intensions to completely go full steam with a new fitness approach only to grow bored with the redundant nature of cardiovascular workouts and have difficulty fitting them into their schedule. Interval training is a great way to accomplish more in less time by combining short bursts of intense activity into your regular workout. By keeping the “slow” intervals at an even higher pace, it turns into high-intensity interval training, and may help you burn more calories in less time.
Here is a suggestion;
20 minute circuit with 4 consecutive exercises for one minute per exercise.
Begin with a bodyweight exercise like a push-up. Next try an intense power cardio exercise like a jack-squat or an Atomic mountain climber. Next a suspension resistance exercise like a TRX squat-row combo. Lastly a 20 yard shuttle run.
The benefits of interval training are only enhanced by boosting the intensity. You burn more calories because your heart rate climbs higher as you perform your circuit, and alternating intensity from all-out blast to a moderate pace helps the body exceed its anerobic threshold. Alternating power and endurance intervals allows your body to adapt faster to new circumstances, which may increase overall performance. Overall high-intensity interval training helps increase the amount of oxygen your body can process, allowing you to breathe harder and get more oxygen to your muscles without feeling out of breath. All of these benefits help you raise your overall level of performance which will only help you achieve your weight loss goals.
