Achieving a toned look is a goal many people have. But it's important to realise that your muscles cannot "tone" by training with very high-rep ranges and limited load or doing more cardio.
So there are no special training or nutrition techniques that will directly make your muscles look toned. Achieving more defined muscles basically comes down to slightly increasing muscle size and reducing your body fat percentage so you can showcase your muscles.
This is done through consistent strength/hypertrophy training, controlling your food intake, and being patient. The sooner you accept this and stop looking for the next "8 week faddy transformation", the less frustrated you will be.
