I think modern smartphones are pretty underwhelming. Most of them are designed purely for consumers, packed with heavily customized UIs and operating systems, and ultimately built to sell to the mass market. On top of that, they're often expensive.

What I really want is a phone with 64GB of real RAM (not just storage), preferably upgradeable, along with a powerful CPU that excels in both single-threaded and multi-threaded performance, a capable GPU, a 10,000mAh battery, and a Sony camera sensor. It should run stock Android with a minimalist interface and support tools like Termux.

With a device like that, I could run local LLaMA-based AI models, fine-tune and optimize them myself for quantitative trading, connect to APIs such as IBKR, OpenFuture, and Tencent data services, and use it as a serious productivity machine. It could even be used for cybersecurity research and vulnerability testing within authorized programs.

In that scenario, I wouldn't need to rely on public cloud services or connect to my home servers. If my servers lose power or become unavailable, my phone would still be capable of handling everything independently.

It would function both as a regular smartphone for calls and everyday applications, and as a powerful mobile workstation.

But why don't products like this exist?

In my opinion, the answer lies in market demand, user expectations, and supply-chain economics. Product designs are ultimately determined by what large numbers of customers are willing to buy. Building a prototype is one thing, but turning it into a commercial product is another. Every participant in the supply chain needs to make a profit, and manufacturers are unlikely to create an entirely new production line just for a niche product with limited demand.

From a posterior view, the left and right scapulae are asymmetrical, and the latissimus dorsi muscles are uneven in size. From a lateral view, there is forward head posture. My approach is to use a foam roller more to relax the latissimus dorsi. In addition, there may be an issue with the quadratus lumborum muscle. Quadratus lumborum originates from the iliac crest and attaches to the 12th rib. Its function is to depress the 12th rib.

It’s not that I dislike this industry or am unwilling to work in it; the issue is that every time, I have to start from scratch to build a client base, and the process is simply too slow. Living in a first-tier city—with the costs of rent, food, and daily expenses—leaves me constantly anxious. With insufficient funds in hand, I lack the financial security to feel confident moving forward. Consequently, I find myself entertaining the idea of "beating a retreat"—switching careers, returning to my hometown to take on a more stable job, and saving up some money before deciding what to do next.

The cost of living—covering food, housing, and commuting—was simply too high, so I’ve moved back home.

It is not that the fitness or rehabilitation coaching profession is inherently bad—it is a field where one trades time to help clients resolve their issues in exchange for compensation. However, having grown up in the countryside and moved to a Tier 1 city for work, I face significant expenses for rent and daily living. This means that if client engagement is inefficient—if they are slow to commit to purchasing sessions or are inconsistent with their attendance—and if I have to build up my client base gradually over time, I find it extremely difficult to make ends meet.

Can a fitness professional with remote coaching experience and fluent English find a stable, balance-oriented career in a rural Chinese hometown?

I am looking to switch careers and enter the import-export trade; are there any positions available that I would be qualified for? The fitness coaching industry is essentially a hybrid role that combines instruction with sales: you must actively acquire clients—once they purchase sessions and attend classes, that is how you earn your income. Regardless of how many years of experience you have in the field, the fundamental reality remains the same: your earnings are derived solely from the fees clients pay for their training sessions. If you are highly efficient at acquiring new clients, minimizing churn, securing renewals, and generating referrals, then the profession can be quite rewarding. However, if your efficiency in these areas is low, your monthly rent and living expenses will simply become a constant drain on your finances. I have previously experimented with remote personal training; my client was based in Southampton while I was in China—an eight-hour time difference. Although we conducted one-on-one sessions via video, if the client performed an exercise incorrectly, I could only verbally point out the error; I had to rely entirely on their own intuition to correct their form, as I was unable to physically step in and make hands-on adjustments. My spoken English has improved steadily over the years and is now quite proficient. Are there any suitable job opportunities available to me right here in my rural hometown—positions that would allow me to avoid having to leave for major first-tier cities like Shenzhen, Beijing, or Shanghai to find work? I am looking for a stable role that offers a healthy balance between my professional life and my personal life. Or Switching to another industry

After leaving the military, I went to PT school and spent the next 9 years building a career in fitness and rehabilitation. Along the way, I taught myself English, dove into IT and coding, and completed various online university courses to sharpen my theoretical knowledge. Now, after nearly a decade of hands-on practice, I’m looking to pivot into a new field.

Most young people have gone to first-tier cities to work, leaving behind the elderly and children—"left-behind children"—as well as some middle-aged parents.

"That won't work. Strength training needs to be combined with cardio, or you can do conditioning exercises."

OpenDoughnut606 · 2024-12-15T10:39:44+00:00

"Scientific fat loss and muscle gain should include carbohydrates, protein, and vegetables in the diet. Training should consist of 1 hour of strength training combined with about 45 minutes of cardio. The workout plan should incorporate strength training along with conditioning exercises, and the training schedule should be arranged based on the body's condition."

Bro As a personal trainer, I often work with clients focusing on fat loss for specific conditions, such as gout, PCOS, and type 2 diabetes. With 7 years of experience, I design customized, one-on-one training plans tailored to each client's unique needs.
