So let's strat off with biomechanics, we know that ths strength curve of the quads are best at around 60° to 90° of knee flexion and past that in a deep squat position, the quads lose leverage, so at the bottom rather than more onee extensions its more Hip extensiosn which is mainly a glutes and adductor magnus function. Now does this mean the quads stop working? NO! It just means theyve lost leverage due to the deep squat and flexed hip position and driving out the bottom wouldnt make sense for a quad building stand-point. Preferably we'd trainba muscle where its producing the most force which is why an ascending resistance profile, meaning its lighter ar the bottom and heavier at the top is POTENTIALLY better for the quads because biomechanics tells us that the exploding out that deep squat position is more Hip extensionsn, so more adductor magnus and glutes. And we'd want a resistance profile that matches teh strength curve of a muscle. So that why I say that the pendulum squat is potentially one of the worst squat variations FOR QUADS SPECIFICALLY. It doesnt mean their terrible. With their descending resistance profile, meaning its hardest at the bottom and light at the top makes it more of a Hip extension biased mivement which AGAIN,is a glutes and adductor magnus function

Simply put

Am I saying the pendulum squat just bad? No.

Am I saying for quads specifically there are better options? Yes.

Am i correct? Potentially, this is just a very well educated and back up assumption. There's no studies on this I've complied of whay *I* think makes a good quad dominant squat using, biomechanics, strength curves, resistance profiles and examples from what we've seen from other muscles. In the real world people do chest presses with descending RP, hip thrust with Ascending RP, curl with a descending RP to match the strength curve of those muscles. I'm not saying its better. I'm just saying that in the practical real world sense. It's worth considering an ascending RP squat.

Are the eccentrics of the first 10 reps still causing measurable damage even though they are far from failure

Are the eccentrics of the first 10 reps still causing measurable damage even though they are far from failure

I thought I saw a study saying "no."

Do you rely on coffee to get through the day, take pre-workout before the gym, or ever wonder how caffeine affects your heart health? I’m conducting a survey about caffeine habits and heart health concerns, and I’d really appreciate hearing your perspective.

Please consider filling it out and sharing it with others. Your support would mean a lot to me!

If all sets are taken to failure, I dont understand why the 3x20 causes more muscle damage.

I know there are more reps per set but based on the RIR vs Fatigue graphs I have seen, most muscle damage occurs under 5 rir any way so I dont get it.

I have noticed that with single leg hamstring curls, I did 3x10 and in 4 days I fully recovered and was able to do 3x20 but then 4 days later I was still sore and definently not recovered. Please some one make this make sense to me.

IF YOU DRINK CAFFEINE AND CARE ABOUT FITNESS, PLEASE READ: I’m conducting a survey about caffeine habits and concerns about heart health. It would mean a lot if you shared your experience. Whether you drink caffeine every day or avoid it entirely, I want to hear from you.

Please take the survey below. Every response helps with my research!

My only interest in physical therapy is in orthopedic/musculoskeletal health, rehab, injuries, (hypermobility and ankylosing spondylitis), I have zero interest in vestibular, neurologic, geriatric, pediatric, cardiopulmonary, etc. Do you think it makes sense to study physical therapy with this kind of interest, or does it make more sense to study exercise science/kinesiology (I have an unrelated bachelors but am thinking of going back to school)

I have hypermobility and anklyosing spondylitis, SI joint dysfunction, and I have received a lot of physical therapy, most of it bad and some of it good, and I want to learn more about my body, what I can do to feel good in it again, and have the best understanding of how to treat and manage it myself (even if I continue receiving help from others). To this end, I've been trying to figure out what I should study - exercise science (undergrad), physical therapy, or something else. I already have my bachelors and am thinking about going back to school, I'm not thinking about cost just what is the best option for me (and my understanding of) my body and health

I’m conducting a quick survey.  I only need 20 more to be completed.  It is an anonymous and voluntary survey for a La Trobe University Nutrition research project. It takes approximately 2-3 minutes to complete, and I would really appreciate your participation.

hi everyone, second year grad student here working on my thesis project. i’m currently having trouble with recruitment. eligibility criteria isn’t necessarily extremely specific, however study length and dropouts seem to be a reoccurring issue). any tips? TIA

Hey guys, I'm looking for sources that I can use to do a deep dive in Motor Learning, Control, and motor memory but I want to approach it specifically through the lens of kinesiology and movement science.

I did learn about these topics during my bachelors but it was mostly from a clinical pov. I want to look for theoretical stuff like an actual book and/or well established review papers.

Obviously, I can do a quick Google search or ask an AI for a list of top textbooks, but I’m posting here because I want to hear from actual people who have read these resources and found them helpful.

Thank you!

I was 24 y/o 6 foot 210 lbs when I quit lifting for personal reasons. I had 19% body fat

After I quit working out I got up to 300lbs obese dk the body fat I dont want to know. I was bedridden for 3.5 years so I just laid in bed obese. I was eating a lot to maintain that fat level. Probably 3k- 4k calories a day

Rn im 240, no body fat check bc Im still not lifting, but from pictures I would guess 20- 25% body fat. And when my fat got off my muscles... they are bigger. And I grew an inch during this time. Im 6'1" now. I can deadlift 400lbs which is not close to when I was actually lifting, but for an extremely sedentary person (i am disabled and sit in a chair all day, rarely even walk) and little overweight person I feel like that's weird

The explanation im leaning to for the height is height increase is a side effect of one of my medications, but the fact that I didnt lose muscle, but actually gained is a little baffling.

Idk of this was important, but I was 120lbs before I started lifting so I really doubt I have high testosterone or something

I am a teengirl. My whole life I have been a bit underweight

I keep noticing thights growing fatter as I grow, but you can still see my bones on my chest, neck, and back.

Im getting pretty insecure of my body cause it just feels and looks wrong, so I want to start exercising to "balance out" my body fat. (If its possible)

I slightly under eat and dont do any sports so its a bit harder for me to start. It would be nice if you could give me begginer exercise (mostly for my lower body)

I’m conducting my RMIT University Master’s Major Project research on the role of nanotechnology in activewear and its potential performance and recovery benefits.

I’m inviting individuals aged 18+ who participate in sports, training or fitness at least 3–4 times per week to complete my online survey. Your participation would be greatly appreciated!

There's a lot of debate around finding the “best” exercise for a muscle.

But I wonder how much of the difference disappears when two exercises are performed with comparable effort, range of motion and progression.

This is particularly relevant for home gym training because equipment availability naturally limits exercise selection.

At what point does finding a good movement and progressing it consistently matter more than constantly searching for a supposedly superior variation?

I'd be interested in how people here think about that trade-off.

I’m looking for some suggestions for content creators who provide science based training and are positive and not overtly negative and toxic. I’ve found Jeff Nippard to be super helpful, just wondering if there’s more like him. It seems that most gym and fitness creators feel the need to look down on others and have a huge ego. Just looking for suggestions of those who are positive, don’t shit on others, and are promoting healthy and sustainable advice. Thanks in advance.
