This is good
Finally. Useful, clear information about the elements.
Only 5 burpees in 1 minute? I’d have like 45 seconds of doing nothing.
I'm tired of seeing workouts on YT listed as HIIT when they're medium-intensity interval. Nothing wrong with medium intensity — the actual workouts are great — but it's misinformation. HIIT It Hard is a catchy title though. These trainers should know better than to advertise a 25-30 minute-plus workout as HIIT.
Natacha Océane taught me what HIIT actually is. I have never hated someone so much for 20 minutes and then loved them afterwards. Now I try to spread the Gospel of Real HIIT. So glad you're explaining it too.
I should do HIIT more but I'm working with a body still recovering from chronic pain. Swimming HIIT is not easy😬 Doable, but so much harder than dryland workouts.
HIIT is the way to go.
Does it make sense with HIIT Training, to Train Daily, the Same routines; cardiovascular fatigue, doesn't allow an individual to fatigue the muscle maximally in a single session, so by Training HIIT 4-5 times a Week, the cumulative muscle fatigue over the week, allows an individual to build the strength as well? HIIT makes sense to me, but 1-2 Times a week doesn't; I feel like with HIIT training, it just makes sense to go all in with that routine, when that Training method is the choice.
just did 6 burpees and 1 min rest.. 5 time. feeling great!
I love you dr. Dear . Iran new. Change lran is good
Hello dear❤christmas happy❤
ارتباط و دوستی با شما را دوست دارم❤
سلام عشق یعنی آرامش حال خوب❤
Isn’t this already built in to a hard lifting session?
What is an erg?
So 5 burpees a day will keep the doctor away? Bike 2 minutes hard then 3 min relaxed 4-5 times? I’ll start today.
your hair looks so good here
Steady state for 2 mins and recover for 3, where should my heart rate be during the exertion?
my god, if there was ever someone who could benefit from a little lip filler…
Excellent…Just did SIT (8 burpees ) 2 mins rest each this morning. It was hard but I did it!😊
Dr. Stacy thank you for your knowledge!!! I am almost 52 and making a comeback. Lost 12 lbs and a pant size… thank you 😊 blessings 😊
Do daily HITs?
Before or after weight lifting. Or on days with not no weight lifting?
Is this HIIT or SIIT? I'm so confused
