Subject: RE: Am I working out too hard? At first glance, your z1 seems quite large but if you're using TTB then go ahead and follow it as you like. Regarding the bike. Subtracting 5 would not be a good idea unless you feel your biking and running fitness is equal, even then I would suggest subtracting 10bpm. Using myself as an example. My lactate threshold testing for the run and bike earlier this year showed that I had no decrease in LT for the run but a dramatic LT decrease for the bike...meaning my cycling fitness dropped off more than my running fitness. My run z1 earlier this year was 131-140bpm while my bike z1 was 116-121bpm. |
