Thanks for the advice my good friends.
I think I was a little anxious about deadlifting again. Or maybe it was the pre-workout espresso?
I will work on activating my upper back. Any activation drills and cues that you would suggest??
And what do you mean by air-humping between reps?
Im planning of adding 10 kg every week using the 5 x 5 scheme, and tinkering with my form until I get things right. Once things get heavy I plan to switch over to the 531 scheme as I am doing for my other lifts. I will post another video once I get up to about 90-100 kg where I believe more form issues will arise.
