BOO! In honor of the spookiest day of the year, we challenge YOU to face your fitness fears and confront these scary workouts – yes, that means burpees. They’ll get your heart racing almost as much as running through a haunted house, and they all take 10 minutes or less, so you’ll have no excuse to quit.

We tapped our Spartan SGX Coaches for their favorite sets that boost strength, speed, and performance to prep you for candy-crushing this month. So brave these butt-busting workouts and celebrate Halloween in Spartan style – the hard way.

Put your bodyweight endurance to the test with this heart-pounding set. It's super simple on the front end, but sustain it for 10 minutes and it’ll be scary how strong you get.

"Just like in a Spartan race, the trick is to keep moving and pace yourself," Tai says.

10 rounds:

• 10x Squats
• 10x Jumping Jacks
• 10x Push-ups
  
  

Or try for time:

• Beginner: 10 minutes
• Intermediate: 8 minutes
• Beast: 7 minutes

Be warned: This drop set is particularly frightening. But it gets your heart pumping more than your favorite scary movie, and builds stamina like no other.

Countdown of 10 reps of each move reducing by 1 until workout set is complete:

• 10 Burpees (then 9, then 8, then 7 and so forth)
• 10 Kettlebell Swings (using the Russian Swing Technique)
• 10 V-Ups (can modify to Seated Tucks or Crunches as required)

4. Acid and Sand

No rest for the weary on Halloween. Try this sandbag buster to push your limits and spook the stamina right out of you. 

"Who says you can’t have everything? This isn’t just a running workout, it’s a heavy lifting workout as well," says Fuiten. "Put the pedal down and see how long you can redline."

4 rounds of:

• 400-Meter Run
• 6 Heavy Sandbag Clean to Shoulder (Sandbag can be dropped behind or dropped back to the front but must land and sit on the top of the shoulder to count)
  
  

To gauge the weight of sandbag:

• Beginner = M 50 lbs, F 35 lbs; 8-10 mins
• Intermediate = M 75-100 lbs, F 50-75 lbs; 7-10 mins
• Beast = M 125-150 lbs, F 100 lbs; 7-10 mins
  
  

Lighter weights can be used if needed. The goal is to move through the weighted "obstacle" as fast as possible and get back to a run.

Packing as many reps as you can handle, top off your terrifying set of workouts with this kettlebell killer and see how "monster" you can become. 

"If you are low on time, turn up the intensity!" Cambio says.

Five reps of each exercise for as many rounds as you can for 10 minutes

• Kettlebell Swings x 5
• Push-Ups x 5
• Gorilla Rows x 5
  
  

The goal is to get as many QUALITY reps as possible.
