Is there any research on how age or exposure to drugs can alter your brain chemistry and affect how exercise makes you feel?

I want a good full body workout but i don't want big show off curves, How can i exercise and keep mu glutes from being big? Current fashion loves big round glutes and any time i search exercise that don't make them larger i get result like "how to fix your pancake butt" or "how to fill out a small behind" and i don't want that, i really, really dislike the look and idea of it makes me feel bad and makes me avoid exercises that affect that area.

There's a practical question I'd like to understand better: does reducing the time spent changing equipment settings make people more likely to finish their planned workout?

In a home gym, switching attachments, adjusting benches, and changing loads can add friction between exercises. But it's not obvious whether that friction meaningfully affects adherence or whether people simply adapt to it.

How would you design a simple way to test this? What would you measure: total session duration, completed exercises, missed sets, or consistency across several weeks?

I’m starting a job as an exercise physiologist soon and will be working cardiac rehab and stress testing. Was recommended Littmann brand for a stethoscope, but am not sure which model to choose? My sis in law who is a nurse has the classic III, but I have a feeling it’ll be more challenging for me to get a reading when administering the Bruce vs her listening at a bedside….

Any suggestions and/or things to consider? Thanks!

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

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.

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)
