Here is a FUN workout variation called Pyramid
Do two exercises and keep alternating as you increase the work to rest ratio.
The timer increases and then decreases just like a pyramid.
Entire set takes about 5 minutes.
I created this timer with built in intervals in an app called Seconds Pro:
Sample of exercises:
A- 4 lunges (2 each side) + 2 burpees
*When timer stops, continue the sequence where you left off
for example- if you only did 4 lunges and 1 burpee, when the time starts again continue with the second burpee then back to lunges.
B- 4 plank hip drops (rocking hips side to side, 2 each way) + 4 seated twists (2 each way)
C- 4 jumping jacks + cone run (about 5 yards- set a distance) and back
Grab a buddy and have FUN!
