Some things will make it easier on some folks to get stronger faster than others
1. If you have an athletic background. If you played soccer all of your life, your legs will have had a head start- you should be able to squat more than the average person.
2. Genetics. Your dad played pro football? Most likely you will make gains faster than if your dad was a Wall Street Analyst
3. Coaching. Hiring a quality coach. Not many out there. Find the right one and don't let go,
4.You stick to a program for at least six weeks. Program switching is usually a disaster.
5. Max infrequently. Go in and test every time that you train and you will get weaker.
6. Perform the basics. Honestly, a true beginner can get very strong if they just focus on the squat, bench press and deadlift. Yeah, but Arnold did kickbacks and flies and....are you Arnold? And he did them after the big stuff.
In addition, before you get frustrated at your lack of gains, step back and look at your lifestyle. Are you taking in enough protein and carbs? Are you resting like you should? Visualizing? Getting massages? Watching videos of the top lifters? Talking to the top lifters? I remember that I wanted to squat 800 desperately. I had nobody around me who knew what they hell that they were doing. So I called Dr. Squat, Fred Hatfield on the phone( I searched and searched until I found his number) and he wrote a program for me right then and there, no questions asked. Don't bitch about your lack of gains until you have all of your bases covered.
And push thyself. Watch Cristi and Tracy and Kirk lift. When it looks like they can not get one more rep, they get 10 more reps. That is a huge key, never wimp out. You usually have more in you than you think.
