Low Intensity Steady State Cardio

ByJarrat Wood

Low intensity steady state cardio, LISS, is a prolonged submaximal effort that can be maintained for several minutes, even hours, by relying completely on your aerobic system. HR targets for LISS will vary depending on fitness level, but an effort level of 4-6/10 should be the goal.

 

Why LISS?

 

After a bout of LISS exercise, it is possible you finish without feeling like you have done much of a workout. After all, you’ve only been putting in ~50% effort throughout your session! This is where the misconception of needing to push yourself to your limit every time you work out needs to be forgotten. During a low intensity session, the total work performed (calories burned) and the proportion of fat burned during the session, is much higher than during a moderate intensity session. The low intensity session will also allow you to come back to the gym feeling fresh the next day, and those sessions at the end of the week or end of a long day won’t be so daunting. Often times getting to the gym on those long, busy days is an impractical goal, but a post-dinner walk with your partner, walking the shops on the weekend, or playing games with your kids are easy ways to increase your energy levels, improve your mood and get in a workout without feeling exhausted.

LISS to run the city to surf?

 

For those with long distance aerobic goals, consider this: 80% of the running performed by elite distance runners is actually LISS. The pitfall many people fall into when thinking about a big goal like the city to surf, a marathon, or even an iron man is the typical “no pain, no gain” mantra which leads to a lack of progress over time, increased risk of injury and ultimately many people not achieving their goals. If even world class marathon runners spend 80% of their time training at a low intensity, why should you try to beat your personal best every time you exercise?

 

Want to improve your fitness? Manage your weight? Avoid nausea from pushing yourself to the brink of exhaustion? Sometimes LISS is MORE!

  • Client Success Story: a fracture fairytale

    ByJarrat Wood

    It was about 30mins before the start of the NRL Grand Final between the Rabbitohs and the Bulldogs and one of my clients, Matt and I were lucky enough to be able to catch up before kick-off to have a drink. It was a great day and whilst we were both enjoying the day with separate parties it was great to catch up outside of the gym for a change. We went our separate ways before the game and there was no way to foresee how the night would turn out (for the two teams fighting out the Grand Final and for Matt). Unfortunately, Matt suffered a fracture to his foot whilst running for the train after the game. As it turns out, Sam Burgess wasn’t the only person to have a fracture that night and unfortunately there was no “Glory, glory” for Matt. He was about as shattered as the thousands of bulldogs supporters leaving the ground….. and he isn’t a bulldogs supporter. Matt was disappointed when he called me the next day to deliver the news: “It’s fooked” he said, quoting big Sam. We then set about a plan to keep Matt’s fitness up for the next 6 weeks whilst his foot was in a moonboot (see picture).
