If your purpose is just general fitness, it's just good not to feel sore, which means that you have maintained an existing training state and consumed calories, and there is no obvious delayed muscle soreness after exercise.

If you want to further improve muscle volume and strength, you need to increase the training load. As a result of increasing the training load, the delayed muscle soreness after training will be obvious, and the excessive recovery after exercise will be obvious, and the muscle volume and strength will increase rapidly.
