i improved my LT1 with a lot of base work over this year so it came very close to my LT2. There is just a little gap between these two and as soon as i pass it i get flooded by lactate. My lactate curve shows also a sudden rapid rise at this point but still i can reach very high lactate levels at an all out effort.
Any suggestions how to stretch the area inbetween LT1 and LT2? More medio training or would HIT be the right approach?
Hope somebody can help me.
