To build endurance effectively, consider incorporating methods like progressive overload, where intensity and duration are systematically increased over time. Introducing cross-training activities, such as cycling or swimming, can improve overall cardiovascular fitness while reducing injury risks. Regularly assessing your fitness level and setting achievable goals can provide motivation. Additionally, practicing active recovery days ensures the body can recover efficiently while maintaining activity. Consistency and patience are essential; gradual improvement leads to sustainable endurance gains in the long run.
