So, needing a break and a shower anyway, this was the workout I did just now:
10 close-grip push-ups
10 inverted rows
20 kettleball swings
Rest 1 minute
Repeat 5 times
(The "research" phase involved some Googling to find out just what close-grip push-ups, inverted rows, and kettleball swings actually were.)Immediate results: My arms now feel like licorice, and I'm still breathing hard, five minutes later.
Also, I did the rows, not inverted, with 20-pound dumbbells. There is no way I could lift my body weight. When I get to the point where I can, I guess I'll have to start doing this at the gym. They probably have real kettleballs there, too.
