How to survive a fight against someone tall and fast. In this example, it is 5'5" 140 lbs age 32 old vs. 6'1" 185 lbs 44 yrs old. The smaller person must attack the taller persons legs and stay out of his range. As the taller person strikes back, the shorter person must look for openings and close the gap as quick as possible and get into his comfortable striking range. Although the taller person may be fast, the shorter person must train to be faster, otherwise he will be in great difficulty due to his severe reach disadvantage.
