Forcing your body to do something it’s not ready or willing to do will result in an unfavorable outcome. Listen to your body and make adjustments as needed. The warm up is a great time to check in with yourself and determine what needs preferential treatment. Talk to a coach and figure out a good sub. When you start to get tired in a workout, make adjustments instead of forcing your way through the movement. For example, with KB swings, if you are unable to effectively fire the glutes anymore due to fatigue only allow the arms to go as high as the legs throw them. Don’t try and force a position overhead by contorting your body and pulling with the arms. It’s all about listening to your body and training smart!
