Because it is very easy to be stupid with deadlifts. You should be following these simple guidelines but hardly anyone does: 1. If you are tired/hungover/sick/not feeling well/angry then don't deadlift 2. If you don't have the time to do 3-5 warmup sets then don't deadlift 3. If you don't have time to rest at least 3 mins between sets then don't deadlift. 4. If you can't lift a light/medium weight with perfect form then don't try and go heavy. 5. If you aren't competing and under the instruction of a trained powerlifting coach then don't try and max anything. If you can't do 7 reps with a weight then you shouldn't be doing 5 reps. Likewise if you can't do 3 reps with a weight then you shouldn't be doing 1. Leave 1-2 reps in the bank.
