Can't understand what's a two belt loops. I have the same problem and would like to practice this drill.

Do you use the full length dowel?

Yes, use a full-length dowel, either 36" or 48". When you insert the dowel through your two front belt loops, it will pass over your belt buckle and be parallel to the ground.

Alternatively, you can use a short bungee cord to attach the dowel to the front of your body.

No matter how you secure the dowel, the drill has two benefits:

First, you have an unmistakeable 'visual' of your Hip Turn back and through.

Second, you must swing your arms in timing with this Turn, particularly on the Downstroke. If your Hip Turn is too fast (or too exaggerated) from the Top, the dowel will block the passage of the Hands when they reach waist high.
