Yes (at age 74), but not in 30 seconds. In the study they set an 80 per minute cadence.
If you can do 40 or more pushups your heart health is good. So the research says.
Can any of you old buggers do 40 or more?
Men Who Can Do More Than 40 Push-Ups Far Less Likely To Develop Heart Disease - Study Finds

At age 69, I can do 40 in about 50 seconds. But the last 10 are really hard and I nearly have a heart attack.
It is just physics. The mass of the earth is 5.98 x 10 to the 24 power Kg and when you do pushups you are not pushing up as such but pushing away the mass of the earth. Where as a benchpress you may press say 50Kgs therefore you are pushing away from the the mass of the earth only 50Kgs. F=mxa Force = mass x acceleration (9.8) therefore 50kg x 9.8 = 490 Newtons. If you use the same equation for a pushup against the mass of the earth 5.98 x to the 24th power Kg x 9.8, well that is a heaps of Newtons, so the bench press is easier. Ha!
