Check out this challenging TRX routine written by staffer, Tina Hepper!

This is a fun workout that can be done as a circuit of 1-3 rounds, 12 total reps each exercise, inspired by the training plan for the San Francisco Urbanathlon obstacle race back in the day!

I included options for alternatives that don’t require a TRX strap.

This is a great full body workout that focuses on core strength especially since the TRX requires engagement of the core musculature at all times. Have fun!

Warmup

• Jog 5 mins or jump rope
• 60-100 Jumping jacks
• 5x each l3D lunges forward, backwards, lateral
• Arm circles forward and backwards

Main set:

1. Plank - 12 reps
   TRX Plank Saw
   1. Both legs suspended, arms in a low plank position with elbows on the ground
   2. Glutes and legs and abs tight, hips low but without arching your back.
   3. Slowly move forward and backwards just as much as your lower back can handle it! When it gets hard, squeeze your glutes tighter!

   TRX Low Row

   Difficulty can be changed by stepping forward to a lower starting position (making it harder) or back to a higher starting position (making it easier).
   
   Option without TRX:
   1. Lay underneath a table and assume the same starting position with your hands holding on to the edge of the table. Check if you need a counter weight so it won’t tip over when you pull.
   2. Pull up your body towards the table. 
3. Overhead Squat - 12 reps
   TRX Overhead Squat
   1. Standing position, arms straight up the top of your hands pressing against the straps to avoid slack.

   TRX Lunge:
   1. Facing away from the straps, one leg is suspended and bent at 90 degrees.Arms are pointing straight forward for counter balance.2.
