I'm finding great success with 'reverse' inclined pushups. Feet on floor-body angled 45 degrees while pushing up against a supporting surface like a counter top. I keep my elbows very close to body, chest meeting counter at the sternum, and push up with slow deliberation from the hands while chin is pointed up.
In total I do 10 sets minimum, with the # of reps going to fatigue point- 2 minute breaks between sets. This is primarily a triceps blasting exercise but also a 'lats'/back enhancer. Ideal for beginners/those with no access to a gym - and the small group finding tricep developement hits a wall at some point.
