FAQ

How do I monitor my workouts using Ultralytics YOLOv8?

To monitor your workouts using Ultralytics YOLOv8, you can utilize the pose estimation capabilities to track and analyze key body landmarks and joints in real-time. This allows you to receive instant feedback on your exercise form, count repetitions, and measure performance metrics. You can start by using the provided example code for pushups, pullups, or ab workouts as shown:

import cv2

from ultralytics import YOLO, solutions

model = YOLO("yolov8n-pose.pt")
cap = cv2.VideoCapture("path/to/video/file.mp4")
assert cap.isOpened(), "Error reading video file"
w, h, fps = (int(cap.get(x)) for x in (cv2.CAP_PROP_FRAME_WIDTH, cv2.CAP_PROP_FRAME_HEIGHT, cv2.CAP_PROP_FPS))

gym_object = solutions.AIGym(
    line_thickness=2,
    view_img=True,
    pose_type="pushup",
    kpts_to_check=[6, 8, 10],
)

while cap.isOpened():
    success, im0 = cap.read()
    if not success:
        print("Video frame is empty or video processing has been successfully completed.")
        break
    results = model.track(im0, verbose=False)
    im0 = gym_object.start_counting(im0, results)

cv2.destroyAllWindows()

For further customization and settings, you can refer to the AIGym section in the documentation.

Can I use Ultralytics YOLOv8 for custom workout routines?

Yes, Ultralytics YOLOv8 can be adapted for custom workout routines. The AIGym class supports different pose types such as "pushup", "pullup", and "abworkout." You can specify keypoints and angles to detect specific exercises. Here is an example setup:

from ultralytics import solutions

gym_object = solutions.AIGym(
    line_thickness=2,
    view_img=True,
    pose_type="squat",
    kpts_to_check=[6, 8, 10],
)

For more details on setting arguments, refer to the Arguments AIGym section. This flexibility allows you to monitor various exercises and customize routines based on your needs.

How can I save the workout monitoring output using Ultralytics YOLOv8?

To save the workout monitoring output, you can modify the code to include a video writer that saves the processed frames. Here's an example:

import cv2

from ultralytics import YOLO, solutions

model = YOLO("yolov8n-pose.pt")
cap = cv2.VideoCapture("path/to/video/file.mp4")
assert cap.isOpened(), "Error reading video file"
w, h, fps = (int(cap.get(x)) for x in (cv2.CAP_PROP_FRAME_WIDTH, cv2.CAP_PROP_FRAME_HEIGHT, cv2.CAP_PROP_FPS))

video_writer = cv2.VideoWriter("workouts.avi", cv2.VideoWriter_fourcc(*"mp4v"), fps, (w, h))

gym_object = solutions.AIGym(
    line_thickness=2,
    view_img=True,
    pose_type="pushup",
    kpts_to_check=[6, 8, 10],
)

while cap.isOpened():
    success, im0 = cap.read()
    if not success:
        print("Video frame is empty or video processing has been successfully completed.")
        break
    results = model.track(im0, verbose=False)
    im0 = gym_object.start_counting(im0, results)
    video_writer.write(im0)

cv2.destroyAllWindows()
video_writer.release()

This setup writes the monitored video to an output file. For more details, refer to the Workouts Monitoring with Save Output section.
