Active Isolated Stretching (AIS)

  • Mercola article
    • Method developed by kinesiology and kinesiotherapy specialist Aaron Mattes
    • Hold each stretch for only two seconds to improve circulation and increase the elasticity of muscle joints
    • Examples: walking lunges, squats or arm circles
    • Benefits positively influence power, speed, agility, endurance, flexibility, and strength performance when used as a warm-up
    • Contrast with static stretching which diminishes muscle performance. American College of Sports Medicine advises against static stretching.

Green Sally Up Challenge

Green Sally Up
3 Challenges in a Row

In May 2020, I bought a set of resistance bands to help with performing regressions and decided to test them using the “Green Sally Up Challenge”. This was my first use of resistance bands and I wondered if they would make pullups so easy I could complete the entire challenge. As it turned out, no. Even with the bands, I still rep’d to failure.

  • My challenge video (5/9/20)
  • Fitness challenge done to the tune “Flower” by Moby (official Youtube and Spotify links). The name of the challenge is often called “Bring Sally Up” based on mis-hearing the lyrics which say “Green Sally” not “Bring Sally”. Every time the song says “up”, do the upward movement of the exercise and hold there until the song says “down”, at which point do the downward movement of the exercise and hold there until the song says “up”. Continue until failure or the song ends.
  • Lyrics
    • Verse:
      • Green Sally up, Green Sally down
      • Lift and squat gotta tear the ground
    • Chorus:
      • Old Miss Lucy’s dead and gone
      • Left me here to weep and moan
    • Verse 8x, chorus, verse 5x, chorus, verse 5x, chorus, verse 12x, chorus
  • Meaning of the lyrics – A children’s tune sung by American slaves.

    • Inside (lower) leg with foot slightly forward, supported by foot knife edge. Outside (upper) leg with foot slightly behind, supported by instep. Alternate reps with leg positions reversed (inside leg behind outside leg)
    • Regress by placing support on an object elevated above the floor
    • Regress by bending legs so lever is supported by knees rather than feet
    • Don’t rotate upper body around shoulder
  • Serratus knee raise
    • Use parallel bars, rings or two chairs
    • Lift knees, push shoulder blades out to protraction, rounded back
    • Support with hands (more strength required in front delts) or forearms (less strength required)

Body Fat

Dangers of Extremely Low Body Fat (Jeff Cavaliere)


“Abs are not make in the kitchen but they are uncovered there.”

  • Drink more water
  • Avoid soda – sugar bombs.
  • Avoid fruit juices (only drink occasionally if it’s 100% fruit juice). High sugar. Spikes insulin levels. No fiber to:
    • Help digestion
    • Slow the release of sugar
    • Provide satiated feeling
  • Build muscle
    • Raises your basel metabolic rate. The more muscle you have, the more energy your body burns.
    • Train the big muscles like gluts, quads, chest, lats
  • Eat nuts, berries, veggies, oats

Pistol Squat

Pistol Squat Progressions

Pistol squat is a key exercise because it requires total lower body mobility stability and strength.

Minus the Gym

  • Stretches
    • Hold all stretches for 60 seconds, 2-3 sets per day, to see gradual improvement in your flexibility
    • Calf stretches
      • Variation 1: Heel on floor, toes raised, ball of foot touching stair or wall
      • Variation 2: Stand with ball of feet on a stair step with heels extending backwards off the step. Allow gravity to pull your heel down.
    • Hip flexers: forward kneeling lunge
    • Hamstrings: Stand with knees locked. Bend forward to touch toes or the ground
  • Progressions
    • Work all progressions up to 8 reps (the top of strength-building range)
    • Split squat
    • Single leg kneeling squat. Touch knee to ground at bottom of negative.
    • Elevated single leg squat
    • Assisted pistol squat. Hold onto a pole, door frame, ring. Start with half-rep, then 3/4 rep and full rep.
    • Counter-weighted pistol squats. Hold a weight in front of you for balance.
      • This is a key missing progression in other tutorials.
      • Build up to 8 reps per set with 20-25 lbs (9-11 kg)
      • Then, decrease weight and build up to 8 reps.
