Hey i recently read something about the morning lifting, its on tmuscle so I dont know how credible it is but still worth looking into:
Research on circadian rhythms (your body's internal clock) indicate that the summation of several important anabolic hormones peak at 3 and 11 hours upon awakening. What does that mean in plain English? Well, according to science, if you wake up at 6:00 am, you're at your strongest at 9:00 am and 5:00 pm. And, according to Olympic strength coach Charles Poliquin, your joints — specifically, the synovial fluid that lubricates your joints — require about 3 hours to reach an optimal level of warmth, which will help improve performance while decreasing the likelihood of injury.
Dr. Stuart McGill, a spinal biomechanist and professor at the University of Waterloo, warns people not to perform demanding exercises first thing in the morning. Since discs are hydrophilic, they tend to soak up water and swell overnight, and it's much easier to herniate a swollen, water-filled spine! Therefore, McGill recommends to wait at least one hour after awakening to exercise. That is the critical period since your tissue is superhydrated at that point, resulting in an 18% loss of strength in the spine and risk of injury is heightened!
also talks about a good meal for those workouts, i personally believe in eating before workouts because I feel weak and deflated without any food especially carbs. i know i couldnt lift half of what i usually can with no food in me.
