For a Max HR of 190, this range is 152 to 171. Anaerobic means that your muscles are working beyond your body's capability to supply enough oxygen to them. The lactate being produced by exercise is not being flushed from the muscles and starts to build up within them. When too much lactate builds up, your muscles start to feel tired and may cramp. Lumps of lactate create hard clumps in your muscles and may take several days to get flushed out.
Massage can help break up the clumps and greatly reduce recovery time.
Red Line Zone - this is the zone where you learn to use new bad words. Here you stomp the pedals as hard as you can. Your muscles need more oxygen than your body can provide, and the lactate builds up in your muscles rather than being flushed out by blood flow. For a Max HR of 190, this range is 171 to 190.
