I've discovered a kickass half hour workout routine to Matt and Kim + Blink-182 and this actually works. I've done this 5 nights in a row and am thouroughly satisfied with my results.
Good For Great- Pushups during verses and switch to clap push-ups during chorus
Feeling This- Sit-ups through whole song
Obvious- Plank during verse and pushups during chorus
I Miss You- Penguin crunches
Violence- Sit-ups during verses and push-ups during choruses.
Stockholm Syndrome- Wall sit
Fallen Interlude- Water and cool down time.
This seriously works. My abs were really shitty lookiing, but now they're getting a wee bit more defined.
For Push-ups, you could also try Anthem Part 2. Which would make it so that you could just omit the crunches altogether
This is a workout that I do without questioning, every single night, unless I have some prior engagement and I don't get home until extremely late.
I dare you to try it. Bet ya can't do it!
