A weighted march in place involves standing upright while holding weights, such as dumbbells, in each hand. Lift one knee towards your chest while maintaining balance and stability. Alternate legs, mimicking a marching motion, while keeping your core engaged and your back straight. Continue marching in place for the desired duration or number of repetitions, focusing on controlled movements and maintaining proper form throughout. This exercise targets the muscles of the lower body, including the quadriceps, hamstrings, and glutes, while also engaging the core for stability.
