Start with hands just outside shoulder width and level with wrists. Keep abs braced and hips slightly tucked under to keep back straight. Slight tension in the legs to support the hips. Knees sat further back than Box pushup.
Start to bend arms so elbows naturally go back at around 45 degrees, shoulders come down towards fingers.
Shoulders come down to elbow level, keeping body braced.
Push through the hands to return to the start position.
