You need to be hitting the weights at least three days per week. The research says that at the very least, training a minimum of two days per week is needed to maximize muscle growth. How you structure your workouts and the amount of days you devote to strength training depends on your current fitness level.

Is it OK to train every day?

How much is ideal? A weekly day of rest is often advised when structuring a workout program, but sometimes you may feel the desire to work out every day. As long as you're not pushing yourself too hard or getting obsessive about it, working out every day is fine.

How often should I train and rest?

It's recommended to take a rest day every three to five days. If you do vigorous cardio, you'll want to take more frequent rest days. You can also have an active rest day by doing a light workout, like gentle stretching.
