How many times per week should you workout?
Of course my answer will always be depends:
depends on your goals
depends on your lifestyle
depends if you're a professional athlete or if you combine your workouts with other types of sports.
And many more factors.
Generally speaking ideally you would do 2-3 strength training workouts per week.
However (and this might be unpopular opinion) i do believe that even once in 2 weeks will be better than nothing.
Find your way, start working out and improve your life and health.
