Boston Marathon doesn't mean you can loosen your strength.by @fonzian 😊 If you don't use it, you lose. What I felt during hybrid training was that keeping heavy weights really helps to keep my muscle density.Occasionally, there was a day when we had a rough weight, saying, “I ran 14km today”, “I'm speeding today.” At the end of this month, 55 miles a week, up to 405 pounds will be taken. #Running #Running Tips #Lunge #Jogging #Learning posture#Running injuries #running reinforcement #maraton #runningismylife #running
