+# Counting Bicep Reps
+
+
+### AIM 
+To track and count bicep curls in real time using computer vision techniques with OpenCV and Mediapipe's Pose module.
+
+### DATASET LINK 
+This project does not use a specific dataset as it works with real-time video from a webcam.
+
+
+### NOTEBOOK LINK

+
+### LIBRARIES NEEDED
+
+??? quote "LIBRARIES USED"
+
+    - OpenCV
+    - Mediapipe
+    - NumPy
+
+--- 
+
+### DESCRIPTION 
+
+!!! info "What is the requirement of the project?"
+    - The project aims to provide a computer vision-based solution for tracking fitness exercises like bicep curls without the need for wearable devices or sensors. 
+
+??? info "Why is it necessary?"
+    - Helps fitness enthusiasts monitor their workouts in real time.
+    - Provides an affordable and accessible alternative to wearable fitness trackers.
+
+??? info "How is it beneficial and used?"
+    - Real-time feedback on workout form and repetition count.
+    - Can be extended to other fitness exercises and integrated into fitness apps
+
+??? info "How did you start approaching this project? (Initial thoughts and planning)"
+    - Explored Mediapipe's Pose module for pose landmark detection.
+    - Integrated OpenCV for video frame processing and real-time feedback.
+    - Planned the logic for detecting curls based on elbow angle thresholds.
+
+??? info "Mention any additional resources used (blogs, books, chapters, articles, research papers, etc.)."
+    - Mediapipe official documentation.
+    - OpenCV tutorials on video processing. 
+
+
+--- 
+
+### EXPLANATION 
+
+#### DETAILS OF THE DIFFERENT FEATURES 
+    - Pose Estimation: Utilized Mediapipe's Pose module to detect key landmarks on the human body.
+    - Angle Calculation: Calculated angles at the elbow joints to determine curl movement.
+    - Rep Tracking: Incremented rep count when alternating between full curl and relaxed positions.
+    - Real-Time Feedback: Displayed the remaining curl count on the video feed.
+
+
+--- 
+
+#### PROJECT WORKFLOW 
+
+=== "Step 1"
+    Initial setup:
+- Installed OpenCV and Mediapipe.
+- Set up a webcam feed for video capture.  
+
+
+=== "Step 2"
+    Pose detection:
+- Used Mediapipe's Pose module to identify body landmarks.
+
+
+=== "Step 3"
+    Angle calculation:
+- Implemented a function to calculate the angle between shoulder, elbow, and wrist.
+
+
+=== "Step 4"
+    Rep detection:
+- Monitored elbow angles to track upward and downward movements.
+
+
+=== "Step 5"
+    Real-time feedback:
+- Displayed the remaining number of curls on the video feed using OpenCV.
+
+
+=== "Step 6"
+    Completion:
+- Stopped the program when the target reps were completed or on manual exit.
+
+
+--- 
+
+#### PROJECT TRADE-OFFS AND SOLUTIONS 
+
+=== "Trade Off 1"
+    - Accuracy vs. Simplicity:
+        - Using elbow angles alone may not handle all body postures but ensures simplicity.
+        - Solution: Fine-tuned angle thresholds and added tracking for alternating arms.
+
+=== "Trade Off 2"
+    - Real-Time Performance vs. Model Complexity:
+        - Mediapipe's lightweight solution ensured smooth processing over heavier models.
