Bench angles between 30 — 56 degrees appear to produce greater clavicular head EMG amplitudes compared to angles either above or below this range (Barnett et al. 1995, Lauver et al. 2015, Trebs et al. 2010, Luczak et al. 2013).
Assessing the effect
of bench angle, Barnett et al. (1995) found a difference between 40 degrees (superior) and -18, 0 and 90 degrees.
While decline and
flat bench angles both produced greater triceps muscle activity, the flat (0 degrees) condition displayed non-statistically greater muscle activity than all other conditions.
Assessing the effect of grip width, Barnett et al. (1995) explored the difference between the bench press performed with narrow and wide hand spacing, as well as alterations
in bench angle.
-- comfortable shin and knee supports for declining — evenly spaced locks for achieving
desired bench angles — increased weight capacity for heavy workouts — grips to assist with repositioning the body
They reported that the bench press performed with a wide grip and a
decline bench angle produced significantly greater latissimus dorsi muscle activity than the horizontal and incline variations performed with narrow and wide hand spacing.
Therefore, the data appears to indicate that
bench angles between 30 and 56 degrees display superior pectoralis major clavicular head muscle activity than steeper or less inclined variations.
(3) Standard Flat Bench — this does not adjust to give a variety
of bench angles; it is simply a flat bench.
Similarly, Barnett et al. (1995) reported a trend towards greater bench press strength with wider hand spacing during the bench press performed at
different bench angles.
The sternocostal head is more highly activated in the bench press with a wide grip and a decline or
flat bench angle, while the clavicular head is more highly activated in the bench press with a narrow grip and an incline angle between 30 — 56 degrees.
Thus, a narrow hand spacing increases deltoid muscle activity during flat bench press, and anterior deltoid muscle activity tends to increase with increases
in bench angle (Barnett 1995).
Also, you can adjust
the bench angle on every set to emphasize different muscles.
This exercise will take some time and experimentation with
the bench angle before you find a good balance point, but you can begin at about a 60 - degree incline and see how it goes from there.
Alternating between
bench angles and ditching the barbell for a pair of dumbbells once in a while will help you hit as many different fibers as possible and achieve better overall hypertrophy.
Clearly, there is a price to pay for the luxury of being able to adjust
your bench angle.
A Utility bench will give you the freedom to adjust
the bench angle.

The bench press can be classified by the weight implement used (barbell, dumbbell, machine), and the variation (grip width, lifting phase,
bench angle, stability surface).
Comparing the effect of
bench angle, Barnett et al. (1995) explored the difference in latissimus dorsi muscle activity between bench angles of 18 degrees below horizontal, 0 degrees (flat), 40 degrees and vertical.
All of these studies show that greater pectoralis major sternocostal head muscle activity is displayed with
bench angles between -18 and 0 degrees compared with bench presses using inclined bench angles.
Many variations are possible, by altering the loading (barbell, dumbbell, machine), or the technique (grip width, lifting phase,
bench angle, stability surface).
These data indicates that greater deltoid muscle activity is displayed with
bench angles above 28 degrees compared with less steep bench angles, although using a narrow grip tends to reduce this effect.
The sternocostal head is more highly activated in the bench press with a wide grip and a decline or flat
bench angle.
Assessing four different
bench angles, Barnett et al. (1995) found greater pectoralis major sternocostal muscle activity when using an incline bench of 0 (i.e. flat) and -18 degrees (i.e. decline) than with an incline of 40 and 90 degrees, with a narrow grip.
