@FitnessEmpiree We have above average aerobic capacity when we properly design our RT programs, killing 2 birds with one stone

I've noticed that ChatGPT 'checks and balances' Codex perfectly. I'm a vibe coder, and I rely on ChatGPT as my lead tech engineer/consultant/advisor/SME. While Codex has those capabilities as well, I use it more as the 'tech team' to build my products. Therefore, I rely on both equally and love being the messenger between the two. I think as stand-alones they are great, but work better together.

@Hitchslap1 This could be one of the most important questions in the history of mankind

Smh

@DrSuneelDhand Hebrews 11:1 refutes fideism, which is what you're implying

[Jeff Young @JYKines]

@Musclemanhh Why would anyone make plans to stop? Where's is the logic in that?

@Toribabieegirl I went from being a soda-holic, to half juice, half water, and eventually weaned myself off of that. Now it's all water, unless I need caffeine, in which case I'm a hot black tea drinker.

[Jeff Young @JYKines]

@corbin_braun Agreed. It's exactly what my company is doing.

@thsottiaux On a side note: it makes little sense to me to tell the masses that OpenAI "is cooking", and imply that you'll be pushing out products weekly, only to follow that with mostly crickets and small updates for the next two weeks. Just sayin'

@HeartOTXHeartMD @SkylarSkye3 Would you say that your current response to me is the way a 'good person' would respond and react? I would imagine your answer is 'yes', since you likely see yourself as a 'good person', which tells me everything I need to know. Enjoy your day. :)

[Jeff Young @JYKines]

@HeartOTXHeartMD @SkylarSkye3 I didn't state an opinion. I asked you a question.

[Jeff Young @JYKines]

@tunguz I'm 100% certain that your guess has a 50% chance of being right, and a 50% chance of being wrong. :)

[Jeff Young @JYKines]

@HeartOTXHeartMD @SkylarSkye3 How did you objectively determine they were good? Did you have an objective point of reference, or did you go off your own values and perspective?

Clinicians: your patients need more than the advice to “exercise more.” They need a safe, trusted, clinically informed resource that can help them start, progress, and adhere to exercise in a way that matches their medical history, functional status, symptoms, confidence, and readiness.

The Medicine-Rehab-Fitness Institute provides unique, affordable, time-bound virtual medical fitness services designed to serve as an extension of your practice and bridge the gap between clinical recommendations and real-world follow-through.

📷 What MRFi provides:
• Clinically safe exercise prescriptions
• Individualized medical fitness coaching
• Motivation, accountability, and adherence support
• Graduate-level exercise science expertise
• Clinical experience and advanced medical fitness training
• Support for patients with chronic disease, musculoskeletal conditions, and complex health needs

📷 Who we support:
• Cancer survivors
• Cardiovascular, metabolic, pulmonary, and neurological conditions
• Obesity, diabetes, hypertension, and cardiometabolic risk
• Osteoarthritis, chronic pain, and post-rehabilitation needs
• Older adults seeking strength, function, confidence, and independence

📷 For clinicians, referral is simple. MRFi has a HIPAA-aligned clinician referral portal designed to reduce workflow friction and make it easier to connect patients with qualified medical fitness support. After referral, we collaborate, communicate, and provide feedback so clinicians know their patients are being supported, not sent into a black box.

“MRFi gave me the structure and confidence I needed. I knew I needed to exercise, but I didn’t know how to start safely.”
— Tim M., Topeka, Kansas

If you are a physician, nurse practitioner, physician assistant, physical therapist, occupational therapist, registered dietitian, psychologist, chiropractor, or other healthcare professional, MRFi can serve as the virtual medical fitness extension of your practice.
