Hey Raynor,
I'm looking for you to debunk some popular myths in the bodybuilding world.
1) Are Upright Row actually bad for the shoulders?
Not unless you use horrible form or more weight than you can effectively do on your own2) Are Beind-the-neck OHP bad for the shoulders?
Depends on your anatomy - however, this particular exercise is not even that effective and mostly should be avoided due to the high risk low reward nature3) Are DB Flys bad on the shoulder joints?
Not if you adjust your grip to a more neutral position (depending on your anatomy) to accomplish better stability/form.4) Are Leg Extensions bad for the knee joints?
Not unless you overload it and start using the hip flexors and joints to do the work. As long as the weight is not too heavy and you are using good form, it's fine.Side note: What are your thoughts on the butterfly machine vs the pec fly machine?
Both are good, but standard pec flies with dumbbells are superiorAlso, I've finally made the transition to full on body-building from now on after 5 years of powerlifting and I want to get swole, dense, and tick af.
What is in your experiences, your favourite training principles to grow massive (i.e. constant tension via not locking out vs. full contractions via lockout etc...) and what do you recommend in terms of a split, program, or whatever. Please don't suggest any intermediate programs I should 'try' out first. Thanks in advance man.
I understand, there is muscle tension, muscle stress, and metabolic damage in which one can manipulate.
The best way to gain tons of size is with a true hypertrophy routine. IE: huge amounts of volume, don't lock out, constant muscle tension, breakdowns, failures, etc.
