I hurt my foot and have been doing some pool running recently. Does anyone know how it really stacks up to regular running? Is there much form involved? Should you lean forward and kick back to make lots of forward progress, or should you be vertical and use your hands to prevent forward progress? (this is wearing a life jacket without touching the bottom). It certainly seems like the legs high step much more and hence it is really tough to get the cadence up.
Other than recovery work, does it do anything for running fitness and the best way to achieve that, if it can?
