Lately, I've been working on a new routine. I wanted to integrate more conditioning and muscular endurance exercise into what had previously been an extremely power-focused routine. Anyway, in my quest for info to with which to create my new routine, I came across a few not-so-shocking but very helpful ideas.
1. Ab plateau
A lot of us do crunches/situps/flexion exercises while holding a weight plate. But don't hold on your chest. Hold it BEHIND your head. About 5x harder than the other way. For those of you who have been in a "core rut" like myself, you're welcome

2. I *Heart* dumbell snatches
Heavy ones, light ones, whatever, a FANTASTIC full body movement. Try this at the end of your heavy benching/pressing routine (as I did today):
4 Heavy Dumbell Snatches (2 each arm)
10 Push-Ups
No resting, high pace, 2:00 minutes. Repeat as desired.
2 was good enough for me today

Here's another full-body-killer I did in between heavy bag rounds (totaled 4 or 5 times):
6 Dumbell Snatches
10 Clap Push-Ups
15 V-Ups while holding a medicine ball
