The high-intensity training has caused a stir not only in the United States but worldwide. It has revolutionized the entire meaning of working out.

What is CrossFit?

CrossFit can be best described as a lifestyle characterized by effective exercising and proper nutrition. CrossFit takes all aspects of sports and fitness; cherry picks the most effective and applicable to daily lives and integrates them for a total body workout. This can include Olympic lifts, squats, dead-lifts, push-ups, power lifts and gymnastics to name a few. The high-intensity workout can be used to accomplish wide-ranging goals, from better performance to weight loss to improved health. The CrossFit program works for everyone, individuals who are just starting and professional athletes.

Everyone is different, but the demands of this workout program are such that your body is pushed to the limit. Since it combines a mixture of various training disciplines and uses every energy system in your body, CrossFit is one of the most challenging sports. It also leaves your body feeling battered and beaten. Using research-proven supplements can fill the gaps and have significant effects on results. Supplements will help to improve aspects of performance such as endurance, strength, energy capacity and aerobic fitness.

Ingredients to Look out for in Supplements for CrossFit Athletes

BCCAs- leucine, valine and isoleucine are building blocks of muscle, provide your muscles energy, and quicken post-workout recovery.

Beta Alanine – this amino acid improves your workout endurance for harder, more extended training. It thwarts the rise of lactic acid in the muscle to prolong training and delay soreness.

Fish Oil – the omega-3 fatty acids in fish oil reduces inflammation for quicker recovery, builds more muscle, help in fat loss and minimize joint pain.

MCT Oil – burns off excess fat, increases your focus, energy and endurance.

Creatine Monohydrate  – naturally produced in the body, supplemental creatine helps to increase power and strength, letting you train harder. It also increases lean body mass.

L-Carnitine – helps convert fatty acids into energy to improve performance and reduce soreness after intense training sessions.

Magnesium and Zinc – they help in tissue repair and regeneration. Magnesium is essential in calming down the nervous system for better rest.

Multi-Vitamins – multi-vitamins have a wide array of daily vitamins and minerals to cover your bases and give you protection against deficiencies during intense phases of training. They also enhance performance and optimal health.

Glucosamine and Chondroitin – rebuild damaged cartilage and relieves joint pain.

ZMA – enables you to recover faster between workouts and sleep better.

Vitamin D – for optimal performance and health. Our sedentary lifestyles don’t allow us to get enough Vitamin D from sunshine.

Protein Powder – a popular post-workout boost, proteins are the key for strength adaptations, muscle growth, fat loss and recovery.

Caffeine – caffeine has been shown to enhance power output during activities such as cycling, sprinting and weight training.

When combined, studies show that the above ingredients can enhance various aspects of performance.
