I absolutely agree! It made no sense for me from the beginning because Actin a and Myosin never crossover Lengthened partials have already been debunked by the same people who'd been advocating it. I give them respect for running a proper study that proved full ROM is better than lengthened partials.

How many reps is best for hypertrophy

Well said.

Brilliant explanation Doc

Hello Doug. Do you still stand by this rebuttal of sorts of SuperSlow? Your being a subscriber to Drew Baye's HIT List would seem to suggest you don't. Anyway, us fans of yours deserve an explanation, I think. As of late into 2024, do you still try to add a few faster extra reps to the small number of SuperSlow-cadenced reps that you do first? If the actin-myosin coupling-and-uncoupling cycles is the main drive toward hypertrophy, why can you get big and strong without moving at all, with static holds and timed static contractions? If you have to add those extra reps after going to MMF with SuperSlow, what remains of the 12 minutes per week approach to exercise? If just takes a lot longer to add those extra reps. Finally, if there's no science behind the actin-myosin coupling-and-uncoupling cycle theory, why do you regulate your workouts according to such at all? You're the Body BY SCIENCE guru, after all.

This is the thing I’ve always believed about testosterone: the function is assertion and action. Using the yin and ying perspective we have the sleep, food, sun on one side and on the other we have being assertive, taking charge, having initiative and willpower and focus! I’ve yet to hear another Dr besides yourself bring up that aspect of testosterone

i have access to a chest press Matrix brand machine, and in order to make better use of the machine i leave a gap of holes in the weight stack. Problem is with loading more weight since the stick don't reach out the lower weight stack, what can i do?

I have used this since I first thought about 5 years ago I don't go to a gym.I don't run.I just do this.. I'm 77 years old and and in fantastic shape with a great diet. Resting heartbeat 48 Blood Pressure 115 over 56. We've been lied to about a lot of exercise fitness crap... Infimetric and Isometric.Just freaking great stuff.

How many reps do you recommend?

Not my type of workout but i get why its effective

Do you recommend to gap the stuck for all MedX machines or just some?

Great explanation of this. I think many trainees will find dropping all the set-extension techniques will allow them to exercise more frequently without overtraining.

ejaculation is de-spunking

Thank you Doctor!

Circus training 😂

Hi doc. Can I know like why you breathe very fast while exercise? Can you explain physiology behind it?😊

so you are saying that i can take PEDs, do nothing, and STILL gain? hell yeah.

Hey Doc, you got that link to Ted's pe diet lecture? Or a link to the audio book? I wasn't able to find any of the 4 books you referenced in this video. Thanks for the help. You're the best for sharing this great information

A family member stumbled upon the HIT workouts last September, Of course I was skeptical because I have had it chiseled in my memory to work out 3-4 days a week,muliple sets.Now 10 months later I can attest that this is the best workout I have performed.I have read Dr McGuffs book "Body by science" and it has been a blessing.I have also read Mike Mentzer's book .Im 58 and I dont think I was will ever deviate from the HIT workout! Thanks

Doc looks more ripped every time I see him!

Great video...can i do 30 seconds up 30 seconds down??

Great advice Doug! What’s your opinion of Jay Primarolo aka Jay Vincent. Google it

Also the excess duetrium from these seed oils will overtime bust your nanomotors. Leading to mitochondrial dysfunction. Stay away from this toxic oils.

If it doesn’t transfer, why could Michael Jordan get another 6 championship in baseball after he retired from NBA?

What's the last exercise in this video called? Is it a lumbar extension?

Fantastic video . Thank you

Hey doc, I'm curious, have you change your thoughts about cardio benefits?

Just speculating with this

💪

So is this a nod towards volume?

Dear Dr. McGuff - thank your for sharing and caring! Remember you talking about avoiding the „black swan“ ? Is there an update to that topic? Appreciate your solid and intelligent work, Sir! 👊

Love the encouragement! My longest was training 21 clients in a day. Yes, grueling and satisfying. I still love what I do and am in my 25th year (I’m 73) as a HIT trainer. Doug, you’ve been a true inspiration. One day, long ago, we had a conversation. I asked you for 3 tips before embarking on this career. You said, 1) “Rent the smallest sq ft facility you can find and get as busy as hell, 2) get a low back machine because ‘you can’t swing a cat in any direction and not hit someone with a low back problem’, and 3) nobody cares about their chart or your charting. “ Remember? Much appreciated and oh so true!

Thanks Doc 🤜🏼❤️‍🔥🤛🏼

Great observation and encouragement.👍🏼💪🏼

Do we get this stuff for Nautilus Machines?

looking forward to your talk with High Intensity Business tomorrow!

Dr. McGuff, thank you for all of the incredible work you do to lift the health and fitness of so many people. Your combination of evidence based practices, practical advice and confidence inspiring encouragement are a true gift to us all.

A tip for trainers on correcting form errors in a way that is encouraging rather than discouraging: phrase corrections as instruction rather than criticism. Instead of telling them what they're doing wrong, tell them how to do it correctly. For example, say "slower" rather than "too fast", or say "breathe" rather than "stop holding your breath".

Thank you Doug! I needed this today.

I want to get back into training and instruction. Really appreciate this video! 🙏🙏🙏

I've been doing BbScience for about two years now, and it keeps getting better. I've never stuck with one system for this long. Intensity can be trained! Intensity is not something a person either has or doesn't have. My first three or four months were spent getting used to the process and since then I've been able to up the intensity, and with it strength gains, regularly. I was used to strength training going in, imagine how much longer it might take a beginner? If I was helping a beginner I'd have them go for a pretty low level of discomfort, knowing that in a year they'll be spending 20 seconds grinding out that last rep while their arms look like they are going to shake lose.

If I could do 15 daily workouts in a row, every day from Monday to Saturday, I would probably be much less burned out with this wonderful and misunderstood profession. Thanks for the encouragement Doug!!

Thank you

LETS GO DR DOUG

Thank you Doug!!! And I appreciate you right back.

Dr. McGuff! Been waiting for a new video. I’m not a trainer but just wanted you to know I bought body by science. HIT training has transformed me massively. You have given me a lot of knowledge. Think I have watched every video of yours as well. Love this way of training. Thank you for what you do!

IMO Training is uncomfortable becuase it is dynamic and a performance. A static levitation removes all angst and assures success for trainee and ttrainer. But, the trainer profession is out of control and counter-productive in general. The proper protocol requires no tiredness, no challenge, no fatigue and results "dope shit ... falling prey to the narcissists"

Thank you, Dr. I needed to hear that.
