Why HIIT training builds more muscle than cardio

Cardio fs you up!

Long distance runners burn up their glycogen storage and immediately burn amino acids “muscle” for fuel. High intensity interval training of 30 sec burst followed by 2 min of slow recovery spares the muscle Thus lowering cortisol before it brings on gluconeogensis. The breakdown of muscle!

    Hi Stephanie! Big fan. So what do you mean by 2 min recovery? Do you just sit there and stretch then do my 30 sec burst? What about a 30 sec burst then 1 min of rest?

      Hi Cecilia

      Thanks for watchin 🙂

      Ok.. for example if you do sprints for a 30 sec burst then you would followed it with a 1.5 to 2 min easy jog recovery to get cortisol and blood pressure back down. You don’t have to stretch in-between.

    I’ve heard this before; do HIIT instead of cardio. And, from a logical, scientific standpoint, it makes sense to me.

    My dilemma is that the exercise that I enjoy most, that I’m really hooked on, is long distance bicycle touring. While family, work schedule, etc. limit me, I really enjoy riding between 2 and 4 hours per day. My primary reason for wanting to Keto-Adapt is to enjoy the benefits of not having to stop for crap food while cycling around the country.

    I realize that this will slow down my weight loss, as I still have 160 pounds (at least) to lose. But, if I enjoy it, is there anything wrong with continuing to do it, as long as I’ve accepted the consequences to the exercise?

    I’m interested in your thoughts.

    Thanks.

    Hi Stephanie,

    So would you suggest doing HIIT before any steady state cardio?

    I am in the same boat as Tom, as I enjoy trail running on weekends.
    I run mostly between 5 -10km, which is like 30-60mins.
    During the week I do resistance training in the gym and HIIT on the treadmill once a week.

    Will this cause any problems with staying in ketosis?

    Your opinion would be much appreciated!

    Thanks,
    C

      Hey Carla

      The problem with running, cardio, hiit, steady state aerobic exercises and endurance training is that many people do activities likes this to release from stress! Unfortunately pushing your body aerobically to the limit with metabolic derangement can make adrenal function worse. As for as keto adapting on aerobic exercise. The healthier you are the easier it is to keto adapt under stress! Most people do NOT adapt well running, biking, treadmill walking while trying to keto adapt. You must choose you exercise method wisely while in the process of keto adapting!

      Cheers S
