Muscles should be soft and flexible when relaxed, but hard and strong when contracted. The hardness of muscles is related to the amount of fat on top of and underneath them. The lower the body fat percentage, the more defined and hard the muscles will look and feel. Muscles that are hard when relaxed are in a chronically contracted state and are incapable of relaxing, which can cause pain and stiffness.

What You'll Learn

Muscles should be soft and flexible when relaxed
When contracting, muscles should be hard as rock or steel. However, if your muscles are always that hard, you will not be very mobile. You will also have to eat much more because this means there is constant tension in the muscles, which will be burning energy all the time.
To achieve soft and flexible muscles when relaxed, you can try foam rolling or massage to get rid of tightness. However, note that some people have observed that the muscle can still feel hard and maintain symptoms of pain and stiffness after these treatments.
Regular cardio is also necessary to help your body burn calories and decrease the excess fat that can accumulate on top of and underneath your muscles. The lower your body fat percentage is, the more defined and hard your muscles will look and feel.

Muscles should be hard when contracting
When contracting, muscles should be hard as rock or steel. However, if they are always that hard, you will not be very mobile and will have to eat more to compensate for the energy being burned by the constant tension in the muscles.
To achieve hard muscles, it is necessary to decrease the excess fat that can accumulate on top of and underneath the muscles. Lower body fat percentages will result in more defined and hard-feeling muscles.

Hard muscles can be a sign of chronic contraction
Muscles should be soft and relaxed when the body is at rest. This is the ideal state for flexibility and mobility. However, when contracting, muscles should be hard as rock or steel. This is a sign of strength.
People with chronically contracted muscles may feel the urge to stretch, but conventional or dynamic stretching only stretches apart the healthy fibres – the fibres that are capable of elongating – and not those fibres that are hard and in a constantly tight state. Clinical observations have shown that even treatments such as foam rolling or massage may not be effective in reducing muscle tightness in these cases.
To maintain healthy muscles, it is important to find a balance between relaxation and contraction. While soft muscles are ideal for flexibility and mobility, hard muscles are necessary for strength. This balance can be achieved through regular exercise, including at least 150 minutes of moderate-intensity cardio each week, which helps burn calories and decrease excess fat that can accumulate on and underneath muscles.

Hard muscles can be a sign of joint strain
Muscles should be hard when contracting, but soft when relaxing. This is because hard muscles can be a sign of joint strain. When a muscle is hard in a relaxed state, it means the muscle fibres have gone into a chronically contracted state and are incapable of relaxing. This will cause the muscle to feel stiff and hurt because of the strain it puts on joints.
Muscles can become hard due to overuse, fatigue, or improper form. This can lead to a muscle strain, which is a tear in the muscle fibres. Muscle strains can be graded depending on the severity of the injury, with a grade 3 muscle strain tearing all the way through.
To prevent hard muscles and muscle strains, it is important to ensure proper form, adequate rest, and a balanced training routine. This includes incorporating regular cardio to burn calories and decrease excess fat, which can contribute to the hardness of muscles. Additionally, foam rolling or massage can help alleviate muscle tightness and hardness.

Cardio can help muscles feel harder
Muscles should be hard when contracting, but soft and flexible when relaxed. If your muscles are always hard, you will not be very mobile and will have to eat more to fuel the constant tension in your muscles.
However, it is important to note that if your muscles are hard when relaxed, this means the muscle fibres have gone into a chronically contracted state and are incapable of relaxing. This will cause pain and stiffness due to the strain on joints and the lack of pliability within the tight muscle fibres.
