Car-Go’s situation is worse. That much weight can slow you demonstrably. Don’t think so? Run 50 yards and time it. Pick up a 25 lb weight and strap it to your back and repeat the 50. Time that. Much slower. Over time you can develop all kinds of knee and calf problems from that much extra weight added so quickly.

Can we please stop perpetuating this myth of adding muscles = bad for speed? Bo Jackson was one of the fastest players in the NFL and probably played around 230lbs. 100m Sprinters aren’t 160lb guys like the marathoners are (look at Michael Johnson, Maurice Green, Leroy Burrell, etc).

If you add the right muscle gains (legs/core), you can gain speed, especially if you work on fast twitch muscle groups. If you add 25 lbs of fat, of course you’ll be slowed.

My guess is that Car-Go loses 10-15 lbs during the year because, as the posters above noted, it takes a lot of work to build and sustain muscle, and nothing breaks that down faster than running.

But I will say even with all that, 22 lbs is probably the maximum you could gain in that “short” amount of time.

Muscle is caloricly expensinve to maintain. Think about how Captain Caveman had to live. Food was scarce and the human body isn’t going to do anything that makes it require more food. Philiologicly we have not evolved that much. Our bodies do not like to add muscle.

Also, some people have a lot easier time adding weight than others. And also let’s not forget there isn’t a lot of running in baseball, so adding bulk/weight isn’t as detrimental as some sports like soccer/basketball etc. So is it possible, yes. Just not easy.
