Be reborn with better genetics!
Jk. My advice is two fold...
Do them separate from leg day (2 days before or after)
So seated/leg press calves followed by standing.
Go heavy for 12-15 reps full range of motion for 3 sets on each exercise, it should be difficult! After your third set, do a quick set of partials to burn out, very rapid fire reps will occlude the muscle and then feel the blood flow into them!
Also incline walking, running, stairs, etc works your calves. If u Orer train them they won't grow! U use them every day so remember that!
Ps- rest period 30-45 seconds between sets..
