Which is more important cardio training or weight training? The answer is that both are equally important, just for different reasons. They both can help you burn calories, but cardio makes your heart and lungs stronger and strength training can help build muscle endurance and size. Most cardio workouts will help you build some muscle, but weight training can really help you build lean muscle mass.
If your goal is weight loss then both cardio workouts and strength training are very important for seeing, and maintaining, good results. The cardiovascular training helps burn calories and with a calorie controlled diet can help you create the daily calorie deficit needed for weight loss. Vigorous exercise can also help temporarily suppress appetite. Regular exercise will also help you control food cravings and balance hormones.
You should mix your cardio workouts up. Some days you need to be doing longer, slower workouts and the other days you need to hit your workouts hard and fast. Doing a variety of workout styles and intensities will help you build endurance, burn fat and increase your cardiovascular capacity.
Strength training is important for many reasons. You need to have strong muscles so that you can have strong bones and a healthy metabolism. The more muscle you have the more calories you burn even when you are at rest. Strength training can also make you feel stronger and more empowered even before you start seeing results in the mirror. Feeling this way will encourage you to keep moving towards your fitness goals.
If you are trying to lose weight then you should be doing 60-90 minutes of cardio 5-6 days per week. It takes quite a bit of cardio work to assist with weight loss, especially if you are not practicing calorie restriction. You should find a calculator online that helps you find the heart rate you need to sustain to lose weight and burn fat. That heart rate will be different depending on many factors such as age, weight and fitness level.
The amount of weight training you need to do will depend on your goals. You will need to do less weight training if you are trying to build muscle endurance than if you are trying to actually gain muscle weight. For someone who is trying to lose weight without losing lean muscle mass doing weight training 2-3 times per week for at least 20 minutes should be sufficient.
For people who actually want to gain muscle mass it might be best to consult a personal trainer. They can evaluate you to ensure that you have sufficient muscle endurance and strength to being a muscle gaining program. They will then be able to teach you proper techniques to build muscle and get you started on a routine that you may be able to continue later on your own.
No matter what your goals are, both cardio workouts and strength training are important. Both types of workouts can help you meet your fitness goals. Scheduling both into your week will help you get amazing results.
