“Mr. Marchand’s VO2 max was now about 13 percent higher than it had been before … He also had added to his pedaling power, increasing that measure by nearly 40 percent.” Why is it surprising that Mr. Marchand saw this kind of improvement after increasing his cycling training regimen? Because Mr. Marchand is 105. (This fits in nicely with my plan to start exercising regularly when I’m about 102 or 103.)
