"Get Under the Bar" - Dave Tate has a powerful book titled "Under the Bar".
I don't care what you get under, but get under something heavy. Get your hands dirty, lift it, push it, pull it, drag it, carry it, press it, throw it.....I've seen people develop strength by moving many different kinds of "weights", but, those who made the most porgress lifted HEAVY.
There are no two ways around it, you gotta lift heavy weights to develop incredible strength. Strength that you can use in the real world is critical. I've seen some jacked up bodybuilder type fashionistas struggle to move furniture. If you're used to deadlifting, squatting, power cleaning and flipping tires - carrying furniture won't be a problem.
But I saw this during a trip to the beach last summer. These two guys were shirtless and JACKED! But they were wrestling like no tomorrow with the sofa, putting it down every couple of feet....I could tell right away they were not used to ground based movements like I espouse frequently in my Underground Strength Manual - http://UndergroundStrengthManual.com.
There some awesome machines out there, but, nothing beats deadlifts, squats, stone training, strongman work and the like. Still, all of your training must suit your goals and needs, but the one thing about the basics is that they will always work. Stick someone in a small room with nothing but a 500 lb barbell and I guarantee they can make unheard of gains in strength, power and muscle development.
I did it in my Dad's garage using a 300 lb barbell set and you can do it to.
Have you noticed that in these fancy, high tech gyms there are very few strong and big guys? Go to a low tech gym, a hard core gym, and you will certainly find an abundance of big, strong guys.
I've seen both.
I've been able to transform skinny, weak athletes into incredibly strong, rugged, mentally tough, and thickly muscles athletes....all in a garage!
With sandbags, barbells, dumbbells, kettlebells, kegs and stones, we got the job done and shocked tons of people in the process who told us that we needed a gym to make the powerful gains. That just isn't the facts. The facts lie in the results, and we have more than enough to prove em' wrong.
So remember, if you want to make big gains, if you want to get strong, you better get under something, and it better be heavy and challenging.
Let your fear go and make it happen. From this point on, it's all mental!
