...I find that using a lighter weight gives the ability to target my triceps while minimizing chest involvement.
even when i do it with no weight i still feel it mainly in the chest
The issue could very likely be in your form. Try keeping your torso straighter & more
(but not perfectly) perpindicular to the ground.
MOST IMPORTANTLY- keep your elbows tucked close to your sides as this will focus more on triceps.
Flared elbows activate more pectoral fibers.
How about inverted dips (hands facing inwards)?
lol how you gonna do that without an injury?
This was an effective technique that guys used years ago on V-dipping bars, which are quite rare to find in gyms these days.
I’ve tried them on parallel bars and, even with wraps, they tear the piss out of your wrists.
Done correctly, they are a fantastic chest-builder.
