When I do the workouts like Tunnabora, I always prefer a higher cadence than is prescribed. I feel like this is because my legs are weak compared to my cardiovascular system. I am not a well trained athlete, my FTP is only 200, I swim about 2:00/100y and I run tempo at about 8:00 min/mi. My best 5k is just under 23 minutes. I am training for a sprint distance tri and am very new at endurance training.
My question is should I use a higher cadence because the instructions seem to encouraging me to build a higher cadence or should I use a lower cadence in an attempt to strengthen my skinny legs? I want to do what will benefit me the most over the long term. With some resistance I can turn the pedals about 115/min without bouncing and feel comfortable between 100 and 105. 85 feels like a grind.
