Why a gradual restart matters
After a long break, your muscles, tendons, joints and fitness have all reduced, even if you were active before. Jumping back in at your old level overwhelms a body that is no longer used to it, which is the classic cause of excessive soreness, niggles and injuries that derail a comeback. Starting gently and building up gradually lets your body readjust, which is far more effective and sustainable.
Starting sensibly
Begin at a comfortable, manageable level, well below what you think you can do, and build up slowly over weeks. Choose activities you enjoy so you keep them up, and include rest days. Some early soreness is normal, but you should not be wrecked after every session. If you have health conditions or have been inactive for a long time, it is worth checking with your doctor before starting, especially for more intense exercise.
Recovery and massage
Gentle movement, stretching, rest and good sleep support your body as it readjusts to exercise. A massage can ease the muscle tightness and soreness that come with restarting, helping you feel more comfortable and stay motivated. Some early soreness is normal and settles; sharp pain, a specific injury, or pain that does not settle should be assessed rather than pushed through, so you do not derail your fresh start.
Key takeaways
- Your body readjusts to exercise after a break, even if once fit
- Start well below your old level and build up slowly
- Include rest days and choose activities you enjoy
