In general, perform each area for about thirty seconds to two minutes or more. Since I cannot assess you, stay on the areas that need the most work you will stay on the longest. If you have no idea what those are, do this.

1. Glutes/Hip rotators: Or Problem Area #1

Glutes Hip rotators

2. Hamstrings: Or Problem Area #2


3. Hip Flexors/Quadriceps: Or Problem Area #3


4. Adductors: Or Problem Area #4

Ultra fast Warm Up (5 minutes)

Lying alternating knee hugs x10/side

Leg lowering w/band x10/side


Three way lunge x7/side

3 way

 Also note: With each exercise don’t jump right into the weight you will be working with. Gradually increase the resistance with some “warm up sets” before performing getting into the “working sets”.

For example let’s use the barbell back squat. Let’s also say you have 4 sets of 5 reps assigned. Start with an empty bar, then add on weight slowly each set. Once you progress to a weight that is challenging for 5 reps, this would count as your first set. Then you would have three more at that weight.

That’s it! If this article gets at least 400 views I will share day four. If not I am going to hold off and put the focus on some other articles!

If you missed it, here is day one, and day two of the program!
