1 Beginners neednât work their way as high up the warm up sequence (to 95 percent of the working weight) as more experienced lifters.  Warm up sets should be tailored to intensity. For example, a session of 4 sets of squats for 6 repetitions entails a heavier working weight than 3 sets of 12 repetitions. Adjust accordingly.
So, if youâre a beginner to weightlifting (training for less than 6-8 months correctly), stick with 3 times per week. If you are anyone else with pretty much ANY goal, training each muscle group about twice per week is what has been proven to work best in most cases.
