What or who are jad trainers? Hope your not paying them money.
might consider:
Bench...DB's
Dips...weighted
Pec Deck...prefer the ones where the elbows are resting on pads. Much better leverage to hit the pecs .If no pec deck than do DB flys's, slight bend at the elbows.
Try 2 sets of 6-9 reps. It's OK to loosen up your form a bit. At this time in your training do not do inclines. Though a great exercise, for a lot of folks it hits the anterior delts more than the upper pecs. The main focus now is the whole of the chest.
You can do the above movements Tri set style. Take a break of 90 to 120 seconds between the first and second Tri set. Or do pre-exhaustions, which would require doing a set of Pec Decks or DB flys before doing DB benches. Than do PD's or flys before a set of dips. Lots of other training options out there.
A very good total chest exercise is the Pullover & Press. With either a BB or DB. A superior compound movement. I, and others, have used this as the only chest movement in regular workouts. Good Luck.
