Leg Strength Challenge: Deep Lunge Isometric Test for BJJ

You can back squat 400 pounds, but what if I put you in the position you need for a takedown?
I like to gauge strength using positional tests. A good level change and initial takedown movement for BJJ and wrestling looks a lot like this deep lunge position. Developing a strong base here and being able to move well from that position without compromising force or power will put you in better positions and have more effective takedowns.
One of my favorite challenges is to put very strong athletes in a deep lunge isometric hold, and watch their legs melt. Think you can pass?
Leg Strength Challenge
Grab 10 – 20 pounds of weight
Get into a deep lunge, 90/90 position
Lift your back knee barely off the ground
HOLD for 1 minute on each leg
Can you finish 3 sets of this? Very few people can.
Check out the challenge here:

We use positional tests at Grapplers Performance to highlight weaknesses in our athletes that can lead to injury. We then fix them to keep them in control of their body and training like they want.
