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.
The length and intensity of the ideal warm-up are still being debated and researched. Before competition, many athletes perform a lengthy warm-up. For example, before a cycling time trial, you will often find the top cyclists warming up at a high intensity for 30 to 60 minutes or more.
