Close Grip Push Up (on Knees) is a beginner bodyweight exercise for the primary: triceps brachii secondary: pectoralis major (chest), with the anterior deltoids (front shoulders) and core stabilizers assisting. Most lifters train it for 3 to 4 sets of 8 to 15 reps.
Start on your knees with your hands placed close together (narrower than shoulder-width). Keep your back straight and core engaged. Slowly bend your elbows to lower your chest toward the floor while keeping your elbows close to your body. Once you reach a comfortable depth, push through your palms to extend your elbows and return to the starting position. Maintain control throughout the movement and avoid letting your hips sag.
Use the close grip push up on knees after your pressing work, in a home circuit, or as the main triceps exercise when you train without equipment, doing 3 to 4 sets of 8 to 15 reps with 60 seconds rest. It builds triceps and chest strength with about half of your bodyweight through the arms, the right starting point before a full close grip push up.
Place your hands directly under the chest with the fingers pointing forward, squeeze the glutes and lock the hips in line with the knees before the first rep. You are lifting roughly 40 to 50 percent of your bodyweight; once 15 reps feel easy on all sets, progress by slowing the descent to 3 seconds or moving to the full close grip push up for sets of 5 to 8. The most common fault is piking at the hips to shorten the lever, which hides weak triceps, so keep a straight line from head to knees and film a set from the side to check.
Yes, they train the same muscles as full push ups with less load and build the strength to progress. Research shows muscle activation patterns are similar, so treat them as a legitimate regression rather than a lesser exercise.
Close grip push ups place the hands narrower than the shoulders but not touching, while diamond push ups bring the index fingers and thumbs together. The diamond version loads the wrists and elbows more, so the close grip is the friendlier starting point.
A reasonable first goal is 10 clean reps, then 3 sets of 15. Once you can do 15 close grip reps on your knees, you are ready to work on the full version.
