HIIT - 30 s workouts

HIIT in 30 second blocks

A HIIT workout involves short bursts of activity (about 20 seconds) followed by short periods of rest (20 to 40 seconds) and repeated for 10 to 20 minutes. 

Here is a HIIT format, in which you do not exercise for a set time but rather you complete a set number of repetitions in 30 second blocks. 

For example, 5 repetitions and then rest until 30 seconds is up and then start again.

Benefits of HIIT

A HIIT workout should be intense and with minimum rest between sets. This will push your muscles close to anaerobiosis which is the objective of HIIT. 

Pushing your muscles close to anaerobiosis and will force your aerobic oxidative and your glucose uptake systems to become more efficient.

With an appropriately designed exercise, building strength, muscular endurance and cardiorespiratory fitness can be achieved within a HIIT session.

Building a 30 second HIIT workout 

You can build your own routine, depending on your level of fitness, the equipment you have access to and how much time you have to exercise. 

For example, you could perform 5 exercises on a chest press or leg press machine at 30 second intervals and repeat this exercise for 10 minutes. Alternatively, 5 pushups or 10 jumping jacks for 10 minutes. For resistance exercises, limit the number of repetitions to 5 so that you do not rush through the repetitions. For aerobic exercises, perform 10 repetitions to ensure create sufficient intensity. If you are a beginner, 5 repetitions per cycle is sufficient.

After 10 or 15 minutes, you will be exhausted. You can rest and when you are ready, you could start again on the same exercise or move on to another exercise.

Examples


Round Exercise Time (min)  Repetitions per 30s Total reps
1 Chest press machine/ free weights 10  5 100
2Pull down lats 10 5 100
3 Jumping jacks 10 10 200
Total 30 400

Another example (which I recently asked my trainee to follow):

Round Exercise Time (min)  Repetitions per 30s Total reps
1 Slam ball (7kg): slam and press 10  5 100
2Kettlebell (12 kg) swing 10 5 100
3Pec deck fly (9 kg) 10 5 100
Total 30 300

My workout

Here is an example of a 30 second HIIT workout using 20 kg kettlebells and a 6 kg slam ball. 

In this workout, I started heavy with 40 kg kettlebell rows and then worked down to lighter weights (20 kg kettlebell swings and 6 kg medicine ball Hay balers).  This workout will work your upper back, your posterior chain and your obliques and deltoids as well as give a intense workout of your cardiorespiratory system.

Round Exercise Time (min)
 Repetitions per 30s Total reps
1 Double 20kg rows 15 5 150
2 20kg swings 10 10 200
3 6kg Hay balers alternating sides 10 5 100
Total 35 450


Timer

You do need a timer. I use the Android version of Tabata Timer

(https://play.google.com/store/apps/details?id=com.simplevision.workout.tabata)

It is a very easy to use app and it is free.



Advice

Do consult with your medical professional before embarking on a rigorous exercise program.

Lifting above the shoulders

Image
Exercises which involve lifting weights above your shoulders present a risk to your shoulder joint. Injuries can be acute, such as a tear or dislocation or chronic such as a rotator cuff injury or frozen shoulder. But lifting objects above your shoulders is requirement of daily living. We need shoulder strength and mobility to stay functional and active. Strong muscles supporting the shoulder joint can also protect the ligaments and bones of the upper body. Exercise selection and progression are important. For seniors, unsupervised use of overhead pressing with barbells may present a higher risk. Alternatives are dumbbells, shoulder press machines, medicine balls, sandbags and kettlebells. All of these exercise tools help keep your shoulder joint aligned in the neutral position to reduce the risk of injury due to repetitive overloaded inflammation of your shoulder joint. I prefer kettlebell presses as the lift starts from the centre line and the movement is vertical. This is a safer op

Workout: Swings, snatches and double long cycles

Image
Once again, I only had 30 minutes to exercise (plus 15 minutes to warm up). After that it was back to work. So I had to make the workout count. Here is the workout (using 16 kg kettlebells): Round Alternating swings Right hand snatches Left hand snatches Double long cycles 1 30 20 20 5 clean presses 2 30 20 20 6 clean push presses 3 30 20 20 7 clean jerks Note how I changed both the number and style of the overhead press. Such variations can reduce the tedium of exercising. I intended to increase the number of long cycle repeats to 10, but unfortunately ran out of time.

(Tabata) timers and note taking apps to enhance resistance training

  Strength/resistance training is essential for good health and longevity. A loss of skeletal muscle mass leads to immobility and loss of independence and is linked to a decline in our immuno-resiliance, increased susceptibility to infections and chronic inflammatory diseases such as type 2 diabetes, cardiovascular disease and cancers. Two key concepts in strength training are intensity and recovery. One consequence of an intense workout is delirium. Delirium is a disturbance in our mental abilities.  Intensity Intensity is a measure of how hard we work during an exercise. Intensity is a function of the load, the number of repetitions and the length of the workout. As we age, we may have difficulty increasing the load, but we can still continue to maintain and develop strength by increasing the number of repetitions and the length of the workout. Recovery Recovery is the period that our muscles are give to rest in between each set or in between each workout. For this discussion, we foc
