Came off Push-Pull-Legs for my last little cut before beach vacation next month. 2-3kg more to go so easily doable.
Of course, first day of full body workout I directly rekt myself. Did 10min cardio, then started out with deadlift. Did 5 sets of warm up deadlifts (tapering from 8 down to 5 reps). Went to working weight, upon first pull heard a loud bang in my ears coming from my neck. Still did the full workout but have headache since that happened and it hurts when I tense my body during a lift. Luckily still full mobility so I can turn my head and all, hope the pain will disappear in the next 48 hours. Guess I had luck after all.
Sounds pretty serious.
Are you sure your form is ok?
