One of the best videos out there on serving fundamentals. The arrows are so helpful. Thank you.

@healycopter

This was extremely helpful. Netted out a lot of concepts that I was having trouble visualizing.

@michaelingram2549

As someone who served 130+ I would only add that as the hand travels over the bicep try not to let the elbow slide forward slightly otherwise this is a great basis to build from.

Excellent Video. So helpful James. Thank you.

Excellent explantation and demonstration James, thank you.

@selwynthompson5635

Extremely illuminating.

@rachidbaaira9869

great video, great analyse, thanks

@andersflodmark8724

Care to talk some more about the "power triangle"? I feel there is a LOT there that could potentially take a lot of serves to the next level. Nice to hear you stressing Internal Shoulder Rotation AND then pronation... not just pronation.

@davkarimz

Just compared it to myself. I'm actually not bad in the lower half of body (besides lifting my right leg for no reason). Need to open the chest more, lead with elbow more, not collapse as much to the left with my upper body. Finally seeing it. Thanks!

@joclarke17

This video is very helpful. Thanks James

@andrewwarren654

Awesome! Great breakdown, thanks!

@jackquinnes

Why do you mix the two different relevant joints and rotations: that of elbow flexion decreasing the elbow angle under 90 degrees during the pre-trophy/back swing phase and that of shoulder external rotation making the hand 'move over  the bicep'? Keep these two motions clearly separate and that contributes to the validity as well as practical value of your analysis and instruction.

@oceanbronze8399

IMO, One of the best serve instructional videos online especially about the power triangle

@nvideos-bn1mn

this the best explaination it can be . thanks

@svrnclv

excellent video

@KumarSabaratnam-d5d

Excellent demo & explanation but not easy to get it all right as explained. Often the right to left gets shortened as I rush up to hit the ball & lose power as a result.

@namcungvlog1079

thank you tennis drill
