Resistance From Suspended Push Ups
The push up is one of the most basic body weight exercises. You don’t really need any special equipment to work this callisthenic movement, but for those interested in trying new things there are options available at many gyms. A study published in the Journal of Strength and Conditioning Research looks at how suspension training systems affect the push up.
Twenty-eight active college students were tested at angles ranging from zero to 15, 30 and 45 degrees. At the lowest angle, subjects were using about 50.4% of their body weight in the up position and 75.3% in the down position. As the angel increased, the load applied to straps decreased and force increased.
