Running
In general, running is considered the quickest way to lose weight and burn calories, while cycling offers a lower impact on the joints. Furthermore running is considered a better fitness workout as it targets a wider range of muscles. Also, walking is known to be the most social exercise among the three sports as it allows people to engage in conversation during the walk.
So it seems that it is ok to run daily, but lifting every day may not be the best idea. When we lift weights, we actually break down the muscle tissue that can then take several days to repair. You don’t want to overtax your muscles by using them too hard too often. It’s better to take a break in between lifting sessions so that the muscles can recover.
Out of the three triathlon sporting events, cycling kills testosterone the most, followed by running. Cycling decreases testosterone levels because it is a high endurance exercise that causes stress and rapid production of cortisol, a hormone that dampens testosterone production.
Even though the distances in cross-country running are much longer than those in competitive swimming, It is believed that swimming is the more difficult sport. That belief is supported by looking at the number of calories burned. It would take nearly a mile of running cross-country to burn 100 calories. A competitive swimmer can burn the same number of calories in a single 100m race.
There are many endurance activities that most people would consider to be even tougher than running a marathon. Some of these incredibly difficult activities include ultramarathons, Ironman triathlons, mountain climbing, long-distance swimming, and obstacle course races.
Getting sick can really derail your training, but it’s best to make sure you’re taking care of your body. After all, you’re likely drawn to your sport for the health benefits, so do what is needed to stay healthy and competitive.
