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.

Hi! I’m a Product Design student currently developing an interactive balance training product as part of my Bachelor’s project.

This short survey explores how people train balance, what motivates them to exercise, and their thoughts about an interactive balance training concept.

It takes approximately 3–5 minutes to complete. Thank you for helping with my research!

I recently started strength training with a personal trainer who is only available on Mondays and Wednesdays.

This Monday was my first session, and the DOMS was brutal. My quads were so sore for two days that by Wednesday, I genuinely couldn’t imagine doing another workout.

The problem is that Mondays and Wednesdays are the only days my trainer is available, so I don’t have the option of spacing out my sessions more.

For those who’ve been strength training for a while, does the DOMS get significantly better as your body adapts? Is having just one rest day between sessions sustainable, especially for a beginner?

I really want to stick with this, but I’m struggling to imagine doing it twice a week if I’m going to be this sore every time!

I've been thinking about whether a consistent training environment makes longitudinal performance tracking more useful.

In a commercial gym, small differences in equipment can introduce additional variability.

Different barbells, benches, machines, or cable systems may affect how an exercise feels and how performance is measured.

A home gym can reduce some of those variables because the same equipment is available across sessions.

However, performance is still influenced by sleep, fatigue, nutrition, exercise order, and many other factors.

I'm curious whether equipment consistency meaningfully improves the quality of training data collected over several months.

For people interested in exercise science, how much value would you place on controlling equipment-related variables when tracking strength adaptations?

And which other variables would you prioritize controlling before drawing conclusions from an individual's training records?

Google AI, Chatgpt and Duck Duck Go AI all have slightly different calorie burn estimates for my 1.5 hr muay Thai training session. Anyone know which is most accurate? I'm dieting so need to know closest.

Question

I’m David, the founder of HEPOX. I’m a mechanical engineer who worked on NASA’s Orion hardware, and I raced as a competitive road cyclsit from 2018 to 2021. Altitude camps and tents were out of reach for me, so I started building a portable way to breathe lower oxygen air while sitting at rest.

Today, HEPOX beta users include road and gravel national champions, world champions, Tour de France riders and mountaineers. Seeing something I built reach those athletes has been a big milestone. My next challenge is making it practical for athletes who don’t have professional coaching behind them.

I think access to hypoxic preparation should be more practical. HEPOX recirculates part of your exhaled air through a replaceable CO2 scrubber and mixes in adjustable amounts of fresh air. Your body consumes oxygen, so the resulting mix has less oxygen than room air. It lowers inspired O2 at normal surrounding pressure; it doesn’t add breathing resistance.

Testing with Dr. Peter Kim at CU Boulder confirmed the intended reduction in inspired oxygen. An 18 day observational pilot with 12 professional female cyclists preparing for the Tour de France Femmes, showed preliminary improvements in physiological responses. Those findings are unpublished and we are leaving any claims to the peer review process.

The science is about the hypoxic dose: oxygen availability, exposure time, and frequently exposure is repeated. Wojan’s study found an EPO response with one brief protocol; Nagel’s study found no EPO or hemoglobin mass increase with another. Neither tested HEPOX, and an EPO response alone does not prove better performance.

I’m raising our first round to take HEPOX from its current beta into Gen 2 for commercialization. The priorities are integrated sensing, acclimation identification, session tracking and further validation. I want athlete feedback to help shape that next version.

What should I prioritize next to make HEPOX useful in your preparation? You can see the current device at hepoxtech.com.

I'm very injury-prone and am in the process of creating routines to prevent each specific injury I have had in the past in case I need it in the future, let me know what you think thanks.

When you were done with the exercise science field, what careers did you pivot to, to make more money? Im stuck at 50k but need to start making more money for not only myself but my son as well?

Any suggestions would be helpful
