How do I figure out how much protein I need each day?

To estimate your daily protein intake, multiply your body weight (in kg) by a factor based on your lifestyle. Sedentary individuals need less protein, while active people or those training regularly require more to support muscle repair and recovery.

What is the ideal protein intake per kg of body weight?

Protein needs typically range from 0.8 to 2.2 grams per kilogram. Lower ranges suit general health, while higher ranges are better for muscle building, fat loss, or intense physical activity.

How much protein should I eat to build muscle effectively?

For muscle growth, aim for a higher protein intake along with resistance training. Consuming enough protein helps repair muscle fibers and supports consistent strength and size gains over time.

How does activity level affect protein requirements?

The more active you are, the more protein your body needs. Exercise increases muscle breakdown, so higher protein intake helps recovery, reduces fatigue, and improves overall performance.

How much protein do I need for fat loss?

During weight loss, protein intake should be slightly higher to help preserve lean muscle mass. A higher-protein diet can also improve satiety and reduce overall calorie intake.

Can you take whey protein if you are lactose intolerant?

Yes, many people with lactose intolerance can still use whey protein—especially whey isolate, which contains very little lactose and is easier to digest than regular whey.

Why does whey protein cause bloating and gas?

Whey protein can cause bloating if it contains lactose. When lactose isn’t properly digested, it ferments in the gut, leading to gas, cramps, and discomfort.

Which type of whey protein is best for lactose intolerance?

Whey protein isolate or hydrolysed whey is usually the best option because it has minimal lactose and is easier on digestion compared to whey concentrate.

Is whey isolate better than plant protein for digestion?

For many people, whey isolate is easier to digest due to its low lactose and fast absorption, but plant proteins may be better for those with severe dairy sensitivity.

How Much Cardio Do You Really Need?

March 13, 2026 by Bolt Nutrition

Cardio exercise is one of the most popular forms of physical activity for improving overall health, supporting weight management, and increasing endurance. However, many people wonder how much cardio they actually need to achieve their fitness goals. While cardio workouts can help improve heart health and burn calories, doing too much or too little may not produce the desired results.

Understanding the right amount of cardio depends on several factors including fitness goals, lifestyle, workout intensity, and overall training routine. Whether your goal is fat loss, muscle maintenance, or general health, finding the right balance is essential.

What Is Cardio Exercise?

Cardio, short for cardiovascular exercise, refers to activities that increase heart rate and breathing for an extended period. These exercises improve the efficiency of the heart and lungs by enhancing oxygen circulation throughout the body.

Common cardio exercises include:

Running or jogging
Cycling
Swimming
Walking
Jump rope
HIIT workouts
Rowing

These activities help strengthen the cardiovascular system while also contributing to improved endurance and overall physical fitness.

👉 What Is Cardio Exercise and Why Is It Important?

Recommended Amount of Cardio

Health experts generally recommend a balanced amount of cardio exercise each week for maintaining good health.

Most guidelines suggest:

150 minutes of moderate-intensity cardio per week, or
75 minutes of vigorous-intensity cardio per week

This can be divided into multiple workout sessions throughout the week. For example, performing 30 minutes of cardio five days a week is a common and manageable approach.

Cardio for Fat Loss

For individuals focusing on fat loss, cardio can help increase calorie expenditure and support a calorie deficit when combined with proper nutrition.

Moderate cardio sessions combined with resistance training can help maintain muscle while reducing body fat. However, excessive cardio without adequate nutrition or recovery may negatively impact energy levels and workout performance.

A balanced approach that includes both strength training and cardio workouts is often the most effective strategy for long-term results.

Cardio for Muscle Maintenance

People who prioritize muscle building sometimes worry that too much cardio might interfere with muscle growth. While extremely high volumes of cardio may affect recovery, moderate cardio can actually support overall fitness and improve endurance.

Including 2–3 cardio sessions per week alongside strength training can help improve cardiovascular health without significantly impacting muscle development.

Low-Intensity vs High-Intensity Cardio

Different types of cardio workouts can influence how much time you need to spend exercising.

Low-Intensity Cardio

Low-intensity cardio includes activities like walking or light cycling. These exercises can be performed for longer durations and are ideal for beginners.

High-Intensity Cardio

High-intensity workouts such as HIIT involve short bursts of intense effort followed by recovery periods. These workouts are often shorter but can be very effective for improving endurance and calorie burn.

Finding the Right Balance

The ideal amount of cardio varies for each individual. Some people may prefer longer steady-state cardio sessions, while others benefit from shorter high-intensity workouts.

To determine the right balance:

Consider your fitness goals
Monitor your recovery and energy levels
Combine cardio with strength training
Maintain proper nutrition and hydration

Consistency is often more important than the exact duration of each session.

Conclusion

Cardio exercise plays an important role in maintaining overall health and improving physical fitness. The key is finding a sustainable routine that supports your goals without interfering with recovery or strength training progress.

By combining moderate cardio sessions with resistance training and proper nutrition, individuals can create a balanced fitness program that supports endurance, heart health, and long-term wellness.
