Have you ever wanted to keep track of your bicep curl reps in a more accurate and automated way? Well, today is your lucky day! In this article, we will explore how to build a Python script that uses machine learning to count your bicep curl reps using a dumbbell.
Let’s dive right in!

Setting Up the Environment
To start, we need to install a few modules. Open up your terminal or command prompt and type the following commands:
pip install pillow
pip install opencv-python
pip install scikit-learn
These modules will enable us to work with images, process camera input, and utilize traditional machine learning algorithms for our counting task.
Next, we will split our program into four files: an app file for the graphical user interface (GUI), a main file for running the program, a camera file for camera processing, and a model file for the machine learning model.
Building the Camera Class
In the camera file, we will create a class called “Camera” that handles camera processing. We will use OpenCV to work with the camera and capture frames. Here’s a simplified version of the code:
import cv2
class Camera:
def __init__(self):
self.camera = cv2.VideoCapture(0) # Use the primary camera (change if necessary)
if not self.camera.isOpened():
raise ValueError("Camera not found!")
def get_frame(self):
ret, frame = self.camera.read()
if ret:
return ret, frame
else:
return None, None
def __del__(self):
self.camera.release()
This code initializes the camera and provides a method to retrieve frames from the camera. Make sure you have the correct camera index set in the VideoCapture()
function (e.g., 0
for the primary camera).
Creating the GUI
In the app file, we will build the graphical user interface using the Tkinter module. Here’s a sample code skeleton:
import tkinter as tk
from PIL import Image, ImageTk
import cv2
from camera import Camera
class App:
def __init__(self):
self.window = tk.Tk()
self.window.title("Techal Bicep Rep Counter")
# Create GUI elements here
def init_gui(self):
# Initialize the GUI elements here
def update(self):
# Update the GUI and perform counting logic here
def start(self):
# Start the main loop
self.window.mainloop()
if __name__ == "__main__":
app = App()
app.start()
In this code, we initialize the GUI window and define the necessary functions for initialization, updating the GUI, and starting the main loop.
Counting Reps with Machine Learning
To count the reps, we need to create a machine learning model. In the model file, we will use the scikit-learn module to train a linear support vector classifier (SVC) model. Here’s a simplified version of the code:
import numpy as np
from sklearn.svm import LinearSVC
class Model:
def __init__(self):
self.model = LinearSVC()
def train_model(self, image_list, class_list):
self.model.fit(image_list, class_list)
print("Model successfully trained!")
def predict(self, frame):
# Preprocess the frame and make predictions using the model
return self.model.predict([frame])[0]
This code initializes the model and provides functions to train the model and make predictions.
Combining Everything
In the main file, we will combine the camera, GUI, and model to create the complete program. Here’s a simplified version of the code structure:
from app import App
from camera import Camera
from model import Model
def main():
camera = Camera()
model = Model()
app = App(camera, model)
app.start()
if __name__ == "__main__":
main()
This code initializes the camera, model, and GUI, and starts the main program loop.
