How to use rex

Getting started with rex is incredibly straightforward and designed for maximum convenience. There are no complex apps to download or lengthy sign-up processes. Here’s how you can integrate rex into your daily routine:

1. Initiate Contact: Simply start a conversation with the rex AI coach on WhatsApp by texting its official number. This opens a direct line of communication with your personal health assistant.
2. Log Meals Effortlessly: To track your food intake, you can either send a text message describing your meal (e.g., "I had a bowl of oatmeal with berries and nuts for breakfast") or simply snap a photo of your food and send it. The AI will analyze the content and log the estimated calories and macronutrients for you.
3. Track Workouts via Text: Logging your physical activity is just as easy. Send a text detailing your exercise, such as "I did 3 sets of 12 reps of bench press at 150 lbs" or "I went for a 30-minute run." rex will record the workout and factor it into your daily energy expenditure.
4. Receive Daily Reports: At the end of each day, rex automatically compiles and sends you a "report card." This summary provides a clear overview of your caloric intake, macronutrient breakdown, and physical activity, helping you stay aware and accountable.
5. Monitor Progress: rex automatically calculates your Total Daily Energy Expenditure (TDEE) and aligns your calorie targets with your specific goals (e.g., weight loss, muscle gain). You can access a dashboard to see your progress over time and stay motivated.
6. Utilize Free Web Tools: For a deeper understanding of your body's needs, you can visit the rex.fit website to use their free calculators for Body Mass Index (BMI), Basal Metabolic Rate (BMR), and TDEE.
