good job our bin was empty it blew over earlier. Mrs P is stuck on a train. Puffy junior is in a foul mood because i pointed out his meal choice provided 26% of RI of saturated fats...for an entire family. I just want to go straight to bed.
I'm not disagreeing Mark, you're completely right in your principle. I love a session on the rowing machine, if I'm training for a particular race I do it on a Tuesday night. I'm not sure it's totally stress free for the lower legs, you can still put some serious force down through your ankles but it is virtually impact free. In the same session I would do adductor and abductor, upper arms, and neck - very light weights but lots of reps, because in long race my arms and neck suffer before my legs. Another key session for me is the cross-trainer itself but hands clasped behind the back because it unconsciously works the core and improves lower leg stability.
Cycling too..I don't cycle but I know loads of people who cycle more than they run, and turn in very good performances in races
