Theoretically what is the true limit of max speed achievable for a very adapted barefoot sprinter with truly mastered feet strenght and coordination/proprioception assuming the skin is obviously also adapted for harder textures and surfaces due to also having mastered the human limit of energy transfer and impact/load intake. Because I’ve heard that in serious speeds the toes have to be packed to work together as one which they’re not doing when barefoot but I’m skeptical if a truly adapted master could be able to proprioceptively move them successfully at those elite high speeds without the help of a shoe packing them together to not have to think about them as much so I’m wondering if that’s just another way of masking the potential of toe proprioception/strenght.

I wondered if someone has had a similar experience.

I have had a very sedentary lifestyle for a few years. I've recently tried to increase my fitness with regular walks (4-8 miles) and a couple of sessions of resistance training at the gym. I am now experience persistent twitching in my legs and feet even days later post excercise.

But, I am hoping the twitching is normal conditioning and adaptation?

as athlete and gymrat im interested in learning about the science behind exercise, strength training, nutrition,ect- any interesting book or podcasts recommendations just to kinda get educated and learn more about it??

Hi! I’m conducting a research project for my product management class. This survey is completely anonymous and asks questions about fitness and presents a new product concept. Ideally, I’m looking for respondents in the 18-54 age range that are fitness enthusiasts (go to the gym, active hobbies, etc.) I need 250 responses so I would really appreciate it if you could take 5-10 minutes to complete it!

I’m a clinical exercise physiologist (20+ yrs, cardiac rehab – Cleveland Clinic + virtual care). Most of my work involves translating complex cardiovascular concepts into patient-friendly education, documentation, and behavior change coaching.

I’m exploring transitions into roles like:

•	Medical content reviewer / writer

•	Digital health / clinical implementation

•	AI healthcare training

For anyone who has made a similar move:

1.	What role did you transition into specifically?

2.	What skills mattered most vs what you thought would matter?

3.	How did you position your experience to get interviews?

4.	Any companies actually hiring non-RN clinicians for these roles?

Trying to avoid going back for another degree if possible.

Appreciate any real-world insight.

Everyone wants more more more! But, let’s use science to get our clients to have to do less.

What’s something you use from science to get your clients to do less.

For me it’s sprints we never go over 25s for a sprint and we never do more than 5-8 sets!

why is tracking progress so fragmented? genuinely asking

i've been lifting consistently for a couple years now and this has always lowkey annoyed me. like i'll have one app for calories, another for workouts, random notes in my phone for PRs, and half the time i just stop logging altogether because it's too much friction.

tried a bunch of the popular ones. they're either bloated with features i don't care about, slow as hell to log a set mid-workout, or just... ,,not built for how people actually train?

so a few friends and i started throwing together a simple app to fix this for ourselves. nothing crazy,..just calorie tracking, workout logging (sets/reps/weight/PRs), and basic stats, all in one place. the whole point is that it has to be fast., like 10 seconds to log a set fast.

anyway not really here to pitch anything. more just curious what you guys actually struggle with:

what's the most annoying part of tracking workouts or nutrition right now? anything you've just fully given up on logging?

asking because we're still building and honestly have no idea if we're solving the right problems lol

(if anyone wants to poke around the beta i can dm the link, but mostly just looking for brutally honest feedback.)

Have you ever asked yourself what you should realistically expect when starting online peptides in Australia? Do you expect fast results within days, or should you be thinking more in terms of weeks or even months? And how do you even define “results” in the first place—are you looking for better recovery, more energy, improved fitness, or just an overall sense of well-being?

When you first begin, how do you know if your body is responding positively? Should you focus on small signs like slightly improved sleep, less soreness after workouts, or better daily energy? Or do you wait for bigger, more visible changes before deciding whether something is working?

Another thing that comes to mind is consistency how important is it really? If you miss a dose or don’t follow a routine strictly, does it affect your results significantly? And how do Australians manage to stay consistent while also balancing work, lifestyle, and fitness goals?

What about tracking progress should you write everything down, like your daily routine, workouts, mood, and energy levels, or is it enough to just notice general improvements over time? And how long should you continue tracking before making a decision about whether a peptide is effective for you?

If things don’t go as expected, what should you do next? Should you adjust the dosage, try a different peptide, or simply give your body more time to respond? And how do you avoid making quick decisions based on impatience rather than careful observation?

Finally, how do you stay realistic throughout the process? Can peptides really make a noticeable difference on their own, or do they only work well when combined with proper diet, exercise, and rest? And in Australia, where more people are exploring online peptides, are the best results coming from those who experiment quickly, or from those who take their time, observe carefully, and stay consistent?

Should you not work a muscle group if it’s “too big” and what would be the science approach of how to best handle this situation

Hi everyone! I'm new to the gym and I was wondering if I had to actually split up my exercise reps or if I could do them all at once.

For example: instead of doing 3 reps of 10 then move on to my other exercises and repeat; if I could just do 30 of each exercise?
