I lost 15kg by dieting and simply walking fast (6km per hour), I gained my weight again during quarantine and I tried HIIT with hopes of seeing results faster. However, it was too hard for me and I was less motivated, I did have injuries multiple times and it actually wasn't very time efficient for me cause I took longer breaks cause I couldn't keep up. On the upside I did improve my resistance and strength very quickly. I ultimately returned to walking and I just love it in summer, it works well for me

[benjaminx]

HIIT or LISS I guess they never miss huh

[LexesOHara]

I have a love-hate relationship with both. If I do LISS, I prefer HIIT and when I do HIIT I prefer LISS. 😂 Cardio is hardio for me either way, even though I also run marathons LOL.

[bangscutter]

I do weight training as my main "bread and butter" workout, so adding HIIT on top of that would be too much. So I just do LISS at the end of my lifting session as a way to cool down in a way. Helps to reduce muscle soreness too.

[vedlatigid]

The advantage of HIIT is the increase in oxygen capacity, the advantage of LISS is its ability to be used by any person, no matter their level of conditioning. I usually separate its use like this: For obese or unconditioned individuals: LISS. For athletes, trained or competition individuals: HIIT.

So I've been doing hiit often lately but have noticed how exhausted I feel the days following and recovery period takes so long. This makes so much sense

[mthomas]

I actually got better results for fat loss from LISS (probably because I could lift weights 3-4x a week, and still do an hour on the elliptical no problem while watching a baseball game). Still, I tend to prefer HIIT. I just like the feeling of being in really good cardiovascular shape. I like being able to play soccer and basketball for 2hrs without feeling like I'm going to collapse 20 minutes in. I like the way I feel when I'm NOT working out after doing HIIT. I like the way I get totally exhausted and then feel refreshed the next day.

I think we focus so much on fat loss that we often lose sight of the other benefits.

[KenPotter]

I'm sticking with LISS - Less wear and tear on my knees and on my treadmill.

[kathieowen]

How about busting the myth of calorie burning on equipment and calorie burn on Apple Watch or fitness trackers. How correct are they?

[alicerobinson]

As someone who once fell into to the HIIT camp, but fell into running (LISS) I really like this review. For me, it comes done to what fits with your lifestyle - for me, during my post-grad studies, running at low-mod intensities just worked - it gave me something that was and easy interruption/reboot for my studies but i totally respect that others may need something shorter based on time alone. They both work - so go with the option that fits for you.

[kristennowosad]

Thank you for this video. Im so sick of Instagram shoving HIIT down my throat.

[hopezhang]

To me, the point of HIIT is entirely to drive performance. If I always run slowly, I can never run fast, and running fast feels good.

[johnsaville]

When I was younger I enjoyed LISS training and did it regularly in training for 10Ks up to marathon distance and eventually triathlons. I also periodically added in interval sprint sessions. After turning sixty I have found that long distance running irritates my hip and lower back so I have switched to HITT training on the stationary bike, rowing machine and elliptical machine a couple of times per week as well as a couple days of hour long mixed steady state cardio. this combination added to a body building style workout that hits muscle groups twice a week has proven to be very effective. It has eliminated injuries, added variety and combined with a diet in which I substantially lowered processed foods and sugar has delivered great results.

Love this!!!! I’ve had a few different coaches and some have been so insistent on HIIT being the best option I think they forget to think about what works for the client and not just what they have had success with or have been taught is the best option. I always look forward to your myth bust Monday’s!

[hiwalkalone]

I choose walking over anything else. 1 hr, earphones in, surrounded by nature :D

[nabetserq]

LISS everyday 50 min and diet on point. HIIT has never being my thing.

[MichelleRoots]

I love both HIIT & LISS! And include both into my weekly workouts for a well rounded routine!!

[TraveltheRedRoad]

Thanks for this one. I've just come back to the gym after a year out. Previously I had been doing resistance training exclusively, with little or no cardio and pretty much zero attention to diet. Since leaving the gym I put on a massive amount of weight as my eating habits remained the same without any exercise to compensate. I've now returned to the gym with a focus primarily on diet, and split my training session to 1/3 compound weight training, 1/3 LISS then finishing with 1/3 HIIT while aiming for 3-4 sessions a week.

Myth bust Monday videos are the highlight of my Monday

[Kfc_Manager-]

Who else tries to compensate for over eating by over training? sigh
