Following a strapless 5k I decided to try rowing with loose foot straps. I was encouraged to do this as a training technique years ago when i was in a boat crew and I forgot what difference it makes. There's a huge temptation to strap in your feet as tightly as possible, but it's really not necessary. Just looping the straps loosely over the bridge of your feet - literally just enough to stop you flying backwards off your seat - gives you so much flexibility and power if your technique is right.
Does anyone regularly train like this, or has anyone else even tried it?
