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.
Remember to warm up before all resistance training workouts with at least 10 minutes of cardio such as walking or skipping rope. For all weightlifting workouts, exercise opposing muscles groups. For example, on chest and back days, work the pecs of the chest, latissimus, trapezius and rhomboids of the back.
