Read something on peak performance which isn't exactly good:
"At Ohio University in the United States, 18 elite male and 12 elite female rowers were evaluated before and after 14 weeks of off-season training. Half of the athletes engaged only in rowing during this period, while the other half devoted 30 per cent of their training time to resistance training and 70 per cent to actual rowing. Resistance training included standard exercises such as squats and bench presses. Prior to the 14-week period, there were no differences between the groups in maximal aerobic capacity (V02max), muscle power while rowing, or overall muscle strength.
At the end of the 14 weeks, athletes who spent all their time rowing improved their performances and raised V02max by a whopping 11-16 per cent, while strength-trained rowers failed to improve in either area."
Brilliant...
