im 17 and I'm starting to train for triathalons..

recently i've been trying to swim freestyle at my local pool but my shoulders always hurt, which I know isn't normal.

But now thanks to your videos I understand what im doing wrongly.

And it's gonna help me improve my form.

Thanks! :)

@justinkwl Great! Good luck with your training!

This is a very useful lesson, and I understand the fundamental point. But if you say that increased mass [in the water, presumably?] equals increased drag, then why do swimmers swim faster when totally submerged? I'm thinking here of Michael Phelps' famous turns when he always gains on his opponents by swimming longer under water. Thanks in advance.

@scrumpymanjack Good question! I am talking about increasing the mass using a straight arm pull. But to your question Phelps is exceptional, rare in his ability to remain submerged (Natalie Coughlan as well), but I think (no scientific evidence here) the reason is because in the submerged position they are able to streamline from head to toe (unlike swimming- limited arm and leg movements). And I also believe their boyancy from air in the lungs helps sustain speed.

coach, i would describe it more as increasing your profile to the incoming water and hence increasing drag, rather than higher mass increasing drag. cos the mass of your arm is the same whether you are doing open armpit vertical pull or doing the straight arm pull.... good tip nonetheless!

thank you so much
