Hi

Im wondering if anyone can measure my lift lane of this lift.
It is 110kg on the bar by the way.

Just like woth the cross in the female comparision movie.

Best Regards

Ragnar,

I slowed the lift down about 50% so you can see the bar path a little better.

Great bar speed, nice depth of the catch and speed under the bar. It looks like you get the bar a little out in front of your feet at the top of your pull and you have to pull it back towards you to catch it.

Keep lifting!

Wow! Thanks for the great editing.

What program did you use and where can I buy/download(if its freeware) it?

One thing I noticed is that I jump back a bit when I do the final "Pull".

Anyone know why I do it?

Best Regards

Wow, Thanks a lot for that Video Tracey. Now this gives me inspiration to lift even more kg :)

How much does the program cost and where can I find it?

Best Regards and thousand thanks to you!

Ragnar,

I used Sony Movie Studio, but you could do this with any number of video software programs including Windows Movie Maker (free program, but only compatible with Windows XP). Move Maker comes bundled with XP.

Here is the process, it took me about 20 minutes to do your video:
1. Going throught the video frame by frame I saved individual pictures at key points (red dots). I usually do this at the start, about the knee, hip, highest point of the pull, lowest point of the catch and then the full upright position. I usually number these 1-8 (or however many pictures I take).

2. I open each picture in MS Paint (also bundled with any Windows OS), placed the cursor on the end of the bar and note the pixel coordinates at the bottom right of the screen. It will look like this "217,78". You also need to note the size of the video frame (360x240).

3. Open a new picture in Paint, fill paint it royal blue, and then place a dot in another color (red in your video) on each of the coordinates you just noted.

4. Connect the dots with the line maker and save the file.

5. Reopen your video software and import the original video and the just saved picture from paint.

6. Overlay the picture on the video and chromakey the blue color out and render your movie.

You are done. If you want more information on video editing try http://www.windowsmoviemakers.net or http://www.videohelp.com

I think your problem is that you let the bar get to far away from your body during the second pull. To counteract the bar moving away from your body, you have to pull it back towards you. You do this by jumping backwards to create a force in the other direction to bring the bar back. You then have to stop this backward motion of the bar with you arms. You will notice your arms are still moving posteriorly at the bottom of the catch even after stopping the descent of the bar vertically because the bar is still moving a little horizontally.

Try to keep the bar a little closer to your face and chest on the second pull.
