Triceps are possibly my weakest muscle group.
Thats absolutely normal. Apart from physical labor style work and sex, you dont really use those triceps alot.
The bright side of this, is once you start focussing on them in trainings, you can get good results pretty fast, cause of all the unused potential.
lying triceps extentions (done right, you MUST feel it burning in the tricep) , close grip benchpress (hands±20 away from each other, 15 reps, 3/4 sets), and cord pulldowns done correctly (keep the ellbows in place, only move forearms)
Is a good combo of excercises to attack that tricep area.
doing incline or flat benchpresses with dumbels is also an excellent excercise, but they require more advanced development to work well
- you need good balance. if you are starting on triceps, you dont have it. Took me pretty long for a good balance.
- you are only really excercising the triceps if you do a good weight. so you need balance and a chest thats getting somewere
before 20kg dumbel inclines, dont consider it "triceps"
