Keeping fit on board is essential. The boat tends to make sure you are reasonably fit all by itself. But you need more.
When things get exciting on the boat you sometimes realise it would be nice to have a little extra strength to throw around, rather than be thrown around.
We use a TRX Suspension exercise straps for keeping ourselves minimally fit along with a skipping rope and stomach roller for core.
You don’t need much, but a little each day will ensure you stay strong enough to handle those moments when the boat demands more from you.
