Due to my busy schedule and trying to balance family life commitments, I have decided to shift to working out in the morning - around 6am. I have read online article/post that advises against heavy back workouts in the morning - atleast until an hour or two has passed after waking up.
Quoting from Stuart McGill, author of books on back pain and back training, “… the inter-vertebral disks are highly hydrated upon rising from bed; the annulus is subjected to much higher stresses during bending under these conditions. The end plates fail at lower compression loads as well. Thus, performing spine-bending maneuvers at this time of day is unwise. Because the discs generally lose 90% of the fluid they will lose over the course of a day within the first hour after rising from bed, we suggest simply avoiding this period for … bending exercise either for rehabilitation or performance training.” (p. 51, Ultimate Back Fitness and Performance, 3rd ed)
I just wanted to get Dr. Jordan / Dr. Austin’s feedback on this. Has modern research proved otherwise or does this still hold true ? Please advice. Many Thanks.
