How I attained a chad-level physique (and how you can too)

As I mentioned in the thread the seated could potentially bias different heads of the calves.

More movements/exercises>more sets.

I’m doing 2 sets for upper chest regardless so I rather split it up for 2 exercises 1 set than 1 exercise 2 sets to potentially hit more fibers
Theres a study that shows that the soleus grows around the same on both bent knee and straight leg, so there's no point at all in doing a seated calf raise as you're just getting less gastroc gains for nothing.

And if you want to do 2 sets for upper chest you're better off just doing the low to high fly, you're just training the same function
