2. feet on 30 cm box – 70% of bodyweight 
3. hands on the floor– 65% of bodyweight
4. hands on 30 cm box – 55% of bodyweight

Electromyographic Comparison of Traditional and Suspension Push-Ups – 2013 – Snarr
Procedure
– 15 men and 6  women; All subjects were currently physically active with at least six months of resistance training experience
– 4 repetitions
Electrode Placement
– Pectoralis Major Sternal or Middle Head: halfway between the sternal notch and anterior axillary line, approx. 2 cm apart in-line with muscle fibers
– Anterior deltoid: two finger-breadths below the acromio-clavicular joint and angled towards the deltoid tuberosity.
– Triceps Brachii: on the long head of the tricep, approx 2 cm apart following the muscle fibers
Exercises
Standard Pushup – medium width: EMG measured when chest was 2″ from the floor
TRX Suspension Pushup – medium width: EMG measured when chest was level with the hands 
Results
Pectoralis Major Middle Head: Suspension 69.54 ± 27.6 %MVC · Standard 63.62 ± 16.4 %MVC
Anterior Deltoid: Suspension 81.13 ± 17.77 %MVC · Standard 58.91 ± 20.3 %MVC 
Triceps Brachii – Long Head: Suspension 105.83 ± 18.54 %MVC · Standard 74.32 ± 16.9 %MVC
