"Do not wait; the time will never be 'just right.' Start where you stand, and work with whatever tools you may have at your command, and better tools will be found as you go along."
- Napolean Hill
I know it sounds ridiculous, but I've had many kids tell me that they were waiting to start lifting until they were able to afford protein supplements. TRUE STORY! I can't help but laugh when I think about that, but it is really very sad...
Unless you are waiting for a doctor's clearance, don't hesitate to get started on your strength and conditioning goals - start today. You don't need a reverse-hyper machine, or BCAAs, or the membership to XYZ's Gym to make amazing progress. Get creative if necessary, but get busy getting better NOW!
