Love me some “Death By” workouts! These are all about going to that dark place and pushing just a little bit harder than what you think you are capable of doing. V-Ups are a classic gymnastics movement based on a good compression. Relies on strong abs/hip flexors as well as mobile hamstrings/lower back. If your compression is a work in progress, try this with tuck ups in place of full V-Ups.
The classic "Death By" workouts increase every minute, but this workout increase every 30 seconds. This will keep the workout a little more manageable from a time perspective.
Early on, I would use all the extra time between rounds to be spent in seal position keeping abs/hip flexors open pliable. Turn from back to stomach during rest periods to help recover as much as possible to keep fatigue at bay. On V-Up, hands must touch feet for rep to count. Touching knees is good on the tuck up variation.
DEATH BY V-UPS
Every 30 Seconds For as Long as Possible,
1 rep in the first 30 seconds
2 reps in the second 30 seconds
3 reps in the third 30 seconds, etc.
Scale: Tuck Ups
