Athletes Notes

How to approach the lifts

Safety and Form

When building up to their 20 rep weight we recommend doing so with 3 sets of 3-5 reps to help prime their nervous system and body.

Encourage athletes create a strong rack position by keeping hands just outside of should width and also pressing up into the bar with palms (rather than just letting the bar sit up the traps)

Make sure athletes focus on a deep stomach breath before every lift.

It’s not about how fast athletes can complete these, but how consistent they can stay with maintaining form.

Cycle explanation

During this 10 week strength cycle, we will be following a 20-Rep Back Squat progression designed to develop raw strength, muscular endurance, and mental toughness. This classic squat cycle challenges athletes to perform 20 unbroken reps at a progressively heavier load each week, to build both physical capacity and mental grit under the barbell. Work hard and reap the benefits.

Start at the weight listed below for week 1 and progress weekly based on the listed increase for your 1RM.

In Pounds:

1RM………….Increase

<= 120#…….start at 60% and increase by 2.5 pounds every other week (or 2.5 every week)
125-185#…..start at 50% and increase by 5 pounds every week

190-255#…..start at 60% and increase by 5 pounds every week

260-360#…..start at 50% and increase by 10 pounds every week

= 365#……..start at 50% and increase by 15 pounds every week

In Kilos:

1RM…………..Increase

<= 55kg……..start at 60% and increase by 2.5kg every other week
55-85kg……..start at 50% and increase by 2.5kg every week

85-115kg……start at 60% and increase by 2.5kg every week

115-165kg….start at 50% and increase by 5kg every week

= 165kg…….start at 50% and increase by 7.5kg every week

INSTRUCTIONS

These are intended to give you a great “pump” for the day. They are a mix of bodybuilding type movements, some CrossFit style structure and/or movements, and aerobic work.

The intensity is designed to just be MODERATE! It is so you can come and do a workout to get a “pump”, sweat some and get out of breath. Ideally you can hit these with friends as well!

Many of these are from, or built off of, recent workouts Rich has done. You can come and do them on a day when you aren’t feeling like doing as much intensity with our other more CrossFit based tracks, or when you want to change up your bodybuilding style. Have fun with them!

Do NOT perform this with the rest of the bodybuilding track. It is meant to be done alone for the day. We recommend performing these as the ONLY bodybuilding for this day and the following day (i.e. if you do all 3 functional pumps in a week, we don’t recommend doing any other bodybuilding, except for the 3 power lifts – Squat, Deadlift & Press).

See Scaling and Sub Document HERE for calorie conversion chart and recommended substitution options!

Bodybuilding RPE Scale

RPE 1-3 || This should be a weight that an athlete can move with ease throughout the intended rep range.

RPE 4-5 || This is a weight that provides a moderate amount of resistance but the athlete feels like they could double the intended rep range with the weight they chose

RPE 6-7 || This is a moderate-moderate/heavy weight for the athletes. This should provide a challenge for the intended rep range but should not be something that they are worried of failing. The rest needed between sets should be minimal.

RPE 8-9 || This is a near maximal effort for the intended rep range. Athletes should need and want adequate amount of rest between the sets at this RPE.

RPE 10 || This is a max effort for the intended rep range. The athlete should be fully taxed at the end of each set.

Kang Squats with Empty Barbell

Back Squat

8 sets: 5 reps @ 80% of 1RM

*Rest 2:00-2:30 b/t sets

Elevated Toe Double DB Romanian Deadlift

*Rest 1:00-1:30 b/t sets

*Build to a moderate weight; stay the same or build across

Focus: Use a small plate or slant board under toes of each foot. Holding dumbbells in each hand, push the hips back, lowering the dumbbells down the front of the legs until the end ROM is hit (or the low back begins to round out). Straps are allowed to be used so that grip is not a limiting factor for sets. If mobility doesn’t allow for toes to be elevated, perform reps with non-elevated toes.
4 sets: 10 reps – RPE 7

*Rest 1:00-1:30 b/t sets

Front Racked Barbell Box Step-Ups

*Rest 1:00-1:30 b/t sets

*Build to a moderate weight; stay the same or build across sets

Focus: With a bar in the front rack position and a 20” box, step up on top of the box to full extension. Repeat on the opposite side. Taking a breath in and breathing out as the step is completed will assist in stability and core engagement.
4 sets: 10 reps (each side) – RPE 7

*Rest 1:00-1:30 b/t sets

GHD Nordic (Hamstring) Curl

*Rest 1:30-2:00 b/t sets

Focus: Control your eccentric (going down) for as long as you can. Sit-up by curling with the hamstrings or pushing off on a box to assist. Don’t try to work above your skill/strength level here. Modify this movement by attaching a band to the GHD and wearing the other end like a backpack to assist in coming up. Place a box in front of the GHD to push off of at parallel if a.) it is too difficult to Sit-up on your own or b.) you fail a rep. Working above your skill level will most definitely increase risk for hamstring cramping.

-if you struggle with this movement and are looking for scaling options: Band Assisted Nordic Curl, Dowel Assisted Nordic Curl, Reduced Range Nordic Curl or Isometric Hold
4 sets: 10 reps – RPE 7

*Rest 1:00-1:30 b/t sets

Standing Barbell Calf Raise

*Rest 1:00-1:30 b/t sets

*Build to a moderate weight; stay the same or build across sets

Focus: Elevate feet so that you can pass below parallel to the floor with the heels. Drive through the big toe at extension. If needed, use rig to guide bar through movement so you don’t lose your balance. *Make sure that platform you are standing on will not flip when standing on edge.
4 sets: 15-20 reps – RPE 7

*Rest 1:00-1:30 b/t sets
