The list of obstacles to training is long but one thing that I’ve seen over and over is the four mentioned above by Gerry DeFilippo are almost always in the top 5. Sleep, hydration, nutrition and time management have derailed almost as many careers as Father Time.
If you find yourself unable to get a good training session in without supplementation to “get you going” I’d take a long hard look at these four items immediately, fix them and then see how you go. My money is on a significant improvement as soon as you get them fixed up.
Now get out there and move some weight!
