Creating a sustainable fitness routine involves setting realistic and achievable goals, establishing a consistent schedule, and incorporating activities that are enjoyable. It’s important to gradually introduce changes to avoid burnout or injury. Additionally, mixing different types of exercises, such as aerobics, strength training, and flexibility work, can help maintain interest and balance. Staying flexible with the plan and allowing for adjustments as needed can further support long-term adherence. Building a support system or engaging with a community can also enhance motivation.
