i actually discovered a effective way to warm up when i was weightlifting som years ago. instead of doing 2-3 lighter warm up sets, i would rather put on more weight than i would lift for my work set. for example if my work set was 100kg, i would load on 140kg and just do some partial reps. that way the 100kg would feel so much lighter.
based on that experience, i think that the traditional way to warm up isnt the best way. preparing the nervous system for heavy lifting this way is very effective.
anyone else tried this too?
