Strength training can still lead to some improvements in muscle strength and endurance, even with unhealthy nutrition. However, the results may not be as significant or sustainable compared to when combined with a balanced and nutritious diet. Unhealthy nutrition can hinder muscle recovery, increase the risk of injury, and limit overall performance during strength training. Therefore, it is important to prioritize a healthy and balanced diet to maximize the benefits of strength training. **

"Fitness natural" refers to achieving physical fitness and wellness through natural and holistic means, such as regular exercise, a balanced diet, adequate rest, and stress management. It emphasizes the importance of avoiding artificial enhancements or shortcuts, and instead focuses on sustainable and healthy lifestyle choices. This approach promotes overall well-being and longevity, rather than just physical appearance or short-term results. **

It depends on the individual's fitness level, goals, and overall health. For some people, combining kickboxing and strength training may be too much exercise, leading to overtraining and potential injuries. It is important to listen to your body, give yourself adequate rest and recovery time, and consult with a fitness professional to create a balanced workout routine that aligns with your fitness goals. **

One can still be considered a natural bodybuilder if they consume whey protein, as long as they do not use any other performance-enhancing substances or drugs. Whey protein is a natural and widely accepted supplement in the bodybuilding community, and it is derived from milk. As long as the individual's training and nutrition are natural and drug-free, they can still be considered a natural bodybuilder. **

Based on the information provided, it is not possible to determine if the bodybuilder is a natural calisthenics athlete or not. The fact that he has been training for 10 years and has a muscular physique does not necessarily indicate the use of performance-enhancing substances. It is important to consider that genetics, diet, and consistent training can also contribute to achieving a muscular physique. Without further information or evidence, it would be unfair to make assumptions about his training methods. **

Hard foods become soft when cooked because the heat breaks down the tough fibers and connective tissues, making them easier to chew and digest. On the other hand, soft foods can become hard when they are exposed to high heat or long cooking times, causing the moisture to evaporate and the sugars to caramelize, resulting in a firmer texture. The changes in texture that occur during cooking are due to the denaturation of proteins and the breakdown of starches and other molecules in the food. **

Sushi is not typically soft and slimy. The texture of sushi can vary depending on the ingredients used, but it is generally firm and chewy due to the rice and various fillings like fish, vegetables, or seaweed. The raw fish used in some types of sushi may have a softer texture, but it is not slimy. Overall, sushi is known for its fresh and delicate flavors rather than being soft and slimy. **
