I am currently training in the gym using there standard gym bikes but I am unsure if it is worth it. I come from a rowing background (lightweight 75kg) and while on my usual 20km row which i used to do daily on an erg I would hit 165bmp HR within 15 minutes and Average 169bmp on the bike my legs really burn and i struggle to get the Heart Rate average above 140.
Could this perhaps be the machines or maybe my type of fitness I am bringing, eg) weak legs.I am buying my first road bike in two weeks when my uncle comes to visit (TT rider). I am hoping it will really help my CardioVascular fitness and improve my rowing fitness aswell as being mightly good fun.
doubtful your legs are that "weak" if you did 20k rows as a matter of course, more likely it's because cycling is principally taxing just your legs as opposed to rowing where your whole body get's a good beating and puts greater demand on your heart.
