How many times a week do I need to go to the gym
If you are asking this question a competent coach, the first thing he asks, what is your goal. Because it depends on the frequency of visits to the gym.
Set mass. Features training on the weight that each muscle group needs to give enough time for a full recovery, usually at least a week. Depending on the method of separation of muscle groups (types of split workouts can be different), training on the ground is best done 2-3 times a week. If time permits, some bodybuilders do every day, but every day only work 1 muscle group, not touching her for another 7 days.
Weight loss. For weight loss in the drying period the number of workouts should increase as their intensity. 4-5 sessions is the minimum, and even better to train 6 days a week and take 1 day off. Thus it is necessary to divide the sessions in favor of cardio exercise. For example, 3 times running and 2 times to engage in power. So slimming process will go faster.
The average person that does not have a specific purpose, can train 1-2 times per week if other days carries at least some load — walks, riding a Bicycle or simply walks. This load is sufficient for prevention of exercise and sports.
