Her Routine


"As many reps as possible" is a strategy that asks you to complete a circuit as many times as you can within a given time frame. "You're always moving, and because you need to keep going for the allotted interval, it's a mental and physical challenge." Warm up for a few minutes and give yourself time to cool down afterward, says Valenzuela. Do any of these circuits for 15 minutes. 

Option 1

  • 15 power snatches with barbell
  • 10 burpees

Repeat cycle for 15 minutes.

Option 2

  • 15 air squats
  • 10 burpees

Repeat cycle for 15 minutes. 

Option 3

  • 7 squat cleans
  • 14 double-unders (allow jump rope to pass under feet twice)
  • 21 pushups

Repeat cycle for 15 minutes.
