Re: Definition of 'Fit' ?
Agreed with most of the above.
In the traditional sense I don't regard myself as fit - my running is terrible and I can't lift a bag of potatoes. However...I can easiy spend an hour on the pads or sparring for 6 rounds or so. You get conditioned to the sport. Im my opionion your better off hitting the bag and sparring than doing endless floor exercises.
They help for sure. But you get fit for boxing by....boxing
