🔧 Workflow

After users fill in basic information (age, history of old injuries, duration of posture discomfort) in the mini-program, they are guided to shoot and upload a 30-second full-body front and side video. The AI calls the pose estimation algorithm to automatically identify posture issues such as rounded shoulders, uneven shoulders, and anterior pelvic tilt, generating an annotated evaluation report and 3-5 targeted rehabilitation training plans. The plans come with AR movement demonstrations, and users can use their mobile phone camera to superimpose virtual movement guidance, intuitively comparing the differences between their own movements and standard movements. The next day's schedule and movement correction points are automatically pushed every night. Users clock in daily by uploading training videos, and the AI adjusts the movement intensity week by week. A progress comparison report is automatically generated every Monday. If there is no improvement for 2 consecutive weeks, a manual review reminder is triggered, running through the complete closed-loop of "information submission -> video assessment -> AR plan generation -> progress tracking" every day.

🛠 Setup Requirements

It is necessary to call the MediaPipe pose estimation API or use the open-source project Posturefit to build posture detection capabilities, and use Coze or Dify to build a pipeline for form collection, video uploading, and automatic report generation. Lightweight AR movement display components can be integrated. Professional AR equipment is not required, and ordinary smartphones can achieve the demonstration effect. Technical skill requirements are medium, and with the help of ready-made open-source projects, an MVP can be built within 2-3 weeks. In the early stage, it is necessary to organize a corresponding rehabilitation movement library for 8-10 common posture problems, including movement essentials and taboo instructions. Standard movement video shooting can be completed with a mobile phone, and core investments are in content library building and process testing.

💰 Revenue

Subscription pricing is 99 RMB/month. By publishing vertical short videos on Douyin and Xiaohongshu focusing on rounded shoulder correction and anterior pelvic tilt improvement for traffic acquisition, a single viral video can bring in 500-1000 trial users. Calculated at a conversion rate of 8%-12%, 1000 trial users can convert into 80-120 paid subscribers, generating a monthly income of 7900-11800 RMB, easily achieving a monthly income of 9k per person. Quarterly and annual payment packages can also be launched, with annual payment subscribers enjoying exclusive posture tracking services, further increasing the customer unit price and total revenue.

💸 Cost

The annual fixed cost is 300 RMB for WeChat mini-program authentication fees. Monthly variable costs include about 99 RMB for the cloud development package and about 200 RMB for pay-as-you-go posture detection APIs, totaling about 300 RMB per month. In the early testing stage, the free quota of open-source tools can be used first, reducing costs to as low as 50 RMB/month. The overall marginal cost remains almost unchanged as the user scale grows, and the gross profit margin can reach over 90%.

⏱ Time Investment

Daily investment is about 2 hours: processing training videos uploaded by users from the previous day in the morning, updating posture assessment results and the next day's training plans, and replying to private messages and inquiries from users; shooting and publishing 2-3 short posture science videos in the evening; investing an additional 3 hours per week to update the movement library and optimize assessment algorithm thresholds; and investing 1 hour per month to analyze user data and iterate the service process. Time investment is flexible, suitable for starting an individual side hustle.

🚀 Getting Started

Step 1: Register Douyin and Xiaohongshu accounts, position in the vertical field of "home posture rehabilitation," and publish 3-5 short science videos on posture problems (such as "Test if you have rounded shoulders in 1 minute") to accumulate initial followers and test user demand. Step 2: Use MediaPipe and open-source templates to build a minimum viable posture assessment tool, provide free posture testing services to followers, and collect feedback to optimize assessment accuracy. Step 3: Launch the subscription service, set up a half-price discount for the first 100 subscribers, quickly accumulate initial paid users to validate the business model, and gradually scale up traffic acquisition after running through the minimum closed-loop.

🔑 Keys to Success

✅ Focus on specific niche pain points such as rounded shoulders, uneven shoulders, and anterior pelvic tilt rather than general fitness crowds, precisely matching user needs.
✅ Use vertical short videos to build professional trust, acquire traffic through free posture tests, and then guide monthly subscriptions to lower the user decision-making threshold.
✅ Update the movement library and assessment report templates weekly to enhance service effectiveness, user experience, and user renewal rates.
✅ Establish user posture change comparison archives, using before-and-after evaluation data as case studies to increase referral rates and user retention rates.

⚠️ 风险

⚠️ AI misjudgment of pathological posture issues may lead to safety disputes. A disclaimer stating "recommend offline medical consultation" must be added to the front end of the process to avoid legal risks.
⚠️ Individual energy is limited. Once the user scale exceeds 200 people, service quality will decline. It is necessary to set a subscription limit in advance or recruit part-time manual reviewers.
⚠️ Fitness content review on short video platforms is strict. Medical promotion terms such as "treat" and "cure" must be avoided to prevent account bans from interrupting the traffic acquisition chain.
⚠️ If the posture detection API is billed on a usage basis, a sudden surge in user scale may cause costs to exceed the budget. Backup open-source solutions must be prepared in advance to control marginal costs.
