But if a muscle isn't being fatigued by a movement it isn't going to grow
that's literally not true, growth occurs because of mechanical tension on a muscle. Outside of that, the spinal erectors erect the spine, aka they keep the spine in place. When you do literally anything in the gym you have to erect your spine to avoid momentum and the involvement of other movements. So something as simple as a dumbbell curl activates your erectors. But the point of curls is to train your biceps, so why are we talking about the erectors?
squats train your quads and glutes; bench your chest; OHP your shoulders; so why are we talking about the erectors? If do squats for the erectors you are missing the forest for the trees. You might as well train what you like and what your body mechanics allow you to
Again, nobody gives a toss about serratus because they get indirectly trained with literally anything you do, so why train it directly?
Inb4 "but it's different with weights!"
it literally is, it moves your center of gravity and compresses your body
plus a baby is not the same as an untrained obese adult
You want them to build an imbalance so that when an arbitrary amount of time passes in the gym that they supposedly have enough experience to do compound movements
the big 5s are not the end all be all of training my nigga
the bench is not the best chest movement, the squat is not the best quad movement, and who know what the deadlift trains
some people in fact, are not built for them (aka having long arms for the bench, or long legs for the squat), some get hurt by them, and some plain old don't like them.
a year is a prudent amount of time for a beginner to have a habit for training, and has learned (hopefully) good form and has built work capacity, thus becoming an intermediate and able to experiment with other movements safely. Maybe he goes on to bench and likes it, or maybe he doesn't. But he has learned that training doesn't stop at that, which is going to lead to him still going to the gym and not having a retarded view of what training is
But let me add, these are general recommendations because am not his personal trainer. Maybe he progresses very well in 6 months, so I would jump to this second phase of training. Maybe he doesn't and needs more time. But am not there, so I can only give him a general recommendation. So it's not an arbitrary amount of time
You can make these movements as easy
let me put it like this
a beginner doesn't have the strength or coordination to lift 45lbs over his head, specially those who are obese. So why force them to do so? Let him go to a machine so that he can lift 5lbs and learn coordination
I think if you're so obese that you can't do a push up you just need to focus on weight loss, not lifting weights.
that's true. But training can help with that. As Lyle says "
Weight training is one of the best and fastest ways to deplete muscle glycogen and start getting fat burning pathways running again", so doing 10-15 on a press machine is a good way to achieve that
Of course, this doesn't change the fact that calories in calories out requires a change in diet as well. So it's not a replacement for a high caloric diet
