I've done four squad sessions in the last couple of weeks. All have focused on interval training. I am one of the slowest having only started paddling a year ago. The rest of the squad are fast.
Being slow I have had the benefit of yanda nossiter guiding me. For a new paddler like me she is pushing me to increase my stroke rate and to accelerate onto runs.
The constant flat out paddling then resting is training my body to paddle at a higher and faster rate. The rest is training my heart to drop down and then go up again.
Below is my last squad. I am holding speeds of about 11.5 kmhr over 4-6 minute intervals.
This is using a fenn xt. Without this squad training I would never have been able to do this. Hopefully I can lengthen the time I can hold this speed.
Mind you squad is absolute agony and I would struggle to push myself this hard if I was on my own.
