Railway sleepers, bathtubs and concrete mix.
This is more of an observation than a question. Most people I have seen lift heavy loads use their back (as I observed the other day) as a lever, consequently these folk end up with back injuries.
If there is one thing I have learned from your training manual is how to lift correctly. Weightlifting more specifically barbell training apart from just lifting weight on a barbell in a gym has implications for lifting awkward and asymmetrical loads outside.
Bags of concrete mix here have a mass of 20Kgs, they use to be about 40Kgs however people were breaking their backs and due to OH&S now they are 20Kgs because the majority of folk do not know how to lift correctly. Any object that is more than 20Kgs has to have a warning sign on it.
There are two parts (there are others)I take out of the training, increased strength and lift technique, both of which are essential for injury prevention for lifting any heavy object from the floor, the table, overhead or to the ground.
I removed a railway sleeper from a garden bed the other day about 60Kgs (an awkward lift with no hand holds), I got into a squat position put my hands under and lifted it up like a Scot with a caber and threw it onto the pile with the rest. I moved numerous bags of concrete mix from truck to ground and squatted down with the load. The bathtub about 90 plus kgs, same thing squatted down and lifted it up somewhat like a deadlift. This is all boring crap I know, what I am saying is even though these are light loads lifted incorrectly will cause back injuries.
These are extensions or outcomes from barbell training.
So Mark whether you realise or not (I am sure you do) your training goes much further than just the gym, so again I want to say as I have done before thanks.
