Flys-press-flys (10,10,10) rest 60sec x2 trisets
Keep the fly weight light, press weight enough to complete reps for all sets (important). Moderate-quick pace - slower on the negative.
I also do a seated press/cable fly, but as you're at home flat/incline should be ok
Do this for 4-6 weeks, then switch to supersets. 12 reps for the flys, 8 for the press. Add in an extra set for total of three sets.
Ive just moved onto push-pull phase - so far this structure is working a treat for me for all muscle groups.
Good Luck mate
