HIIT, or High-Intensity Interval Training, has gained immense popularity as a dynamic and efficient exercise approach.

What is HIIT?

HIIT training stands for High Intensity Interval Training – a form of cardiovascular exercise. HIIT training is great for those who are short on time as a way of maximising your time spent in the gym.

Are Cardio and HIIT the Same Thing?

Cardio and HIIT are related, but not the same. Cardio refers to sustained aerobic exercises that elevate heart rate over an extended period, promoting endurance. HIIT involves alternating intense bursts of exercise with short recovery periods, enhancing cardiovascular fitness and also building strength.

How Often Should I do HIIT?

While there’s no specific set of guidelines as to how often you should do HIIT, alternating periods of high-intensity and low-intensity activities at least three times a week as part of your exercise routine is a good rule of thumb to reap its benefits.

What Muscles will I Work With HIIT?

The muscles worked during a HIIT workout are dependent on the exercises included in the HIIT workout. Activities like squats target the lower body, while push-ups focus on the upper body. Mountain climbers work the core, and burpees involve full-body movement. The variety in exercises ensures a comprehensive muscle workout during HIIT sessions.

You could make it a Full Body HIIT, or just include your upper body muscles, the choice is yours!

Can I do a HIIT Workout at Home?

HIIT workouts are versatile. You are able to do them at home or at the gym. If you find you don’t have any equipment to work with at home, a bodyweight HIIT will more than suffice.

How Long Should HIIT Workouts Take?

HIIT workouts take around 30-60 mins, this should include a warm up and cool down in that time.

How Many Calories are Burnt During HIIT Workouts?

The number of calories burned during HIIT workouts varies based on factors like intensity, duration, and individual fitness levels. On average, a 30-minute session can burn around 300-500 calories. However, this can differ from person to person.

How Long After Starting HIIT do you see Results?

Results from HIIT can vary. Some people might notice improved endurance and energy levels within a few weeks. Visible changes in muscle tone and fat loss may take around 4-8 weeks of consistent training. Individual factors like fitness level, diet, and genetics also influence the timeline.
