Hi James,

I love all the work you do and think you have the crossfit stuff figured out better than Glassman on some issues. I was just wondering in your own words how you would describe the difference in programming between your OPT blog, the Natural High CF, and Crossfit Calgary. It is my understanding that you program for all three. I realize OPT is a little more intense, but was wondering if you would mind sharing some of your goals with the different programs you design among the affiliates.

Thanks for all the inspiration and motivation you provide daily!

Part 1:
A. 95#x3x5
B. 105#x3x5
C. 95#x3x5
D. as rx'd

Part 2:
11:10 total work time. (19:10 total elapsed time)

Snatch practice was good, but needs lots more work. Last 2 rounds of Part 2 were fun...

Soren said...

Part 1
A: 40,45,47,47,47 x 3
B: 50,52,55,55,55 x 3
C: 57,57,57 x 3
D: Good mornings with 20 kg x 15x4
Stopped C due to increased knee pain, have been struggling with medial ligament issues for 8-9 months and it is finally coming good but I am not supposed to do any explosive movements and getting too deep on squats. I have learned to stop before it gets to far, patience is hard!
So, have not done part 2, as it just would make it worse!

OPT, thanks for the answer on the speed on the front squat


JPL said...

A. (95x3) x 3
B. (115x3) x 3
C. (135x2) x 3...too heavy
D. SB hip extension/leg curl: 2 sets x 15

- reduced volume had to catch a flight.

Angelo Fosco said...

For the Snatches @ 11x1 does the first "1" refer to the pull? I'm only assuming it does but thought I'd make sure. Thanks!

B-Rad said...

Can you specify what is involved in the Press Cluster for 2010?

many thanks

Andrew said...


Part 1:
A. 95lbx3, 115lbx2, 115lbx3, 125lbx3, 135lbx2
--> Should probably stay lighter and focus on muscling it more? I pulled it over, but felt like it was all hips and not much "muscling" going on.
B. 135lbx3, 135lbx3, 135lbx3, 135lbx3, 135lbx3
--> 3rd rep was always tough, as my grip kept getting narrower throughout the set.
C. 135lbx2, 135lbx3, 135lbx3, 135lbx3, 135lbx3
--> not used to not-dropping the bar after the rep. As always, the negative made it tough, with significant fatigue in the upper back. Need to get strong!
D. 10lbx15, 25lbx15, 25lbx15, 25lbx15
--> love this exercise

Part 2 (15min rest):
- 1min53s (failed at 10DU, then restarted to complete 25 UB)
- 2min22s
- 2min55s (failed at 21DU, then restarted to complete 2 5UB)
- 2min23s
- 2min07s

Burpees tough because of my shoulder problems. Unable to just drop down like I used to. Did all box jumps unbroken. Restarted all 25 when DUs broke. Maybe rested too much between burpees and box jumps since I made each set unbroken rather easily.

joey warren

how's the back? straight up muscle strain or something else?

Chad Hall said...


A: 95, 105, 115, 125, 130(2)
B: 115, 125, 130, 135, 140FFF (couldn't commit)
C: 125, 130, 135, 140, 145
D: rx'd hands at chest.

really happy with the power snatches, felt really good getting under the bar.

Part 2 (rested 5 minutes)
2:14 (miss at 24, 9, 9 then got 25)
Total Work Time: 8:03

The misses at round 2 made me slow down for the next rounds, didn't want to miss again.

Overall good session.

Michael FitzGerald said...

Yeah, Joey, how is the back doing?

Angelo Fosco said...

B-Rad from what I gathered on tuesday from the front squat cluster: A cluster means doing the reps then racking it for 10 seconds then doing the reps again. In this case, 2 reps, rack 10 seconds, 2 reps, rack 10 seconds, 2 reps then rest. Four sets of that. Hope this helps.

B-Rad said...

Thanks Angelo. I appreciate it

1. 52,5 kg / 115#
2. 62% (32,5 kg / 71#)
3. 130% (3,75 kg + 64,5 kg = 68,25 kg / 150#)
4. right: 12 / left: 8, used the DB weight available = 4,3 kg (8,1%)

Spider said...

A1: 95-105-110-115(x3)
A2: UB

B: 6:46- I felt I rested just enough for each set. The last rep of each was just about the max.

C: 10lb x 3

notes: Chest is still pretty sore

OPT said...

kyle, i program only this blog
Brett does the CF Calgary programming, and their is a collection of us that do the CF Natural High blog

all are for different purposes, hope that helps..

joey warren said...

Hey guys, the back has knocked me out for the last couple days, I've been flat on my back, havnt been able to move much, work, or workout. It will get better, its just in spasm right now which is paralyzing. Im doing everything I can to recoover, it will just take some time. Im guessing next week Ill be able to do some light stuff again. Its nothing permanent and I will be going 110% before the comp. Just have to wait and see how quickly I can recover with icing, stretching, chiro... This will really test me! Thanks for the concerns!

James I would like to talk to you about how to get back into this, and maybe a way to make up this coming weekend because I feel I need this volume to feel well prepared for the comp. I will email you when I can move again!

jay rhodes said...

Hit yesterday's 2010 WOD

1k row - 3:29
A few overload FS reps at 225

Part 1.

Front Squat,185


Wow that was tough. My FS 1RM is about 265-275 last time I checked. Bring on the DOMS!!

FS's were broken:
3 UB
Pullups were all UB, piece of cake in comparison.
Back was still a little tight from the deads, makes for a little less stability.

Paul Smith said...


Part 1:

Rested 15 minutes

1. 1:29 missed once on DU's
2. 1:29
3. 1:27
4. 1:26

Curt M said...


Quick question, If a day is missed, should i just skip that day or just to it a day late and keep doing all WODs a day late??


Michael FitzGerald said...

A1. 120/125/127.5/128.5
A2. hand placement - on bum/low back/chest/neck
B. 10:00 - nothing!
C. 25/27.5/30(6/arm) - focused more on eccentric.

1. 1:27
2. 1:29
3. 1:30
4. 1:36
5. 1:32

total working time: 7:35

not sure what happened on set 4, but the clock doesn't lie...must have taken too long in transition. No broken sets, but it was harder as sets got usual.

Felt like I might have been able to put up more weight on the PS if I had gone lighter on the earlier skill progression sets. Not sure if I should have taken that approach or not.


Julian Cruz said...


I recently missed the last few workouts because I was on vacation. I was doing some sprints and pulled my quad. I have good ROM and little pain. I am contemplating taking a few days off but I want to stay on schedule. What do you think I should do?

Alex Duncan said...

Feeling quite under the weather today, will unfortunately have to take today off. Have to try and be very smart about training and health this year. Back tomorrow I hope.

C. 135/155/155/165/165(f)/165

Not much gas. Really slow getting under the bar. I'll see how the recovery goes this afternoon. May skip the metcon if I can't my energy up.

was cautions not to turn my MS into a PS. i just barely got all 3 reps @ 130 so i left weight the same.

running in a 5k tonight so going to skip part 2

d. 15x2

Part B: 9:21 working time. 1:44 on sets 2-3, 1:50 set 4. Used a 24inch box for set 1 so it was much slower ha.

Kickboxing tonight.

Mike Molloy said...


Part 1:
A: 65-75-85-90-95
C: 135-140-145-150(F)-150(F)
D: UB, easy.

Notes: Previous 3RM for Power snatch is 155. Dealing with some serious DOMS from the front squats today made this less explosive than I would have liked.

Part 2:
1- 1:32
2- 1:30
3- 1:20 (there we go)
4- 1:22
5- 1:25

word verification is "restmate." Sounds like something BK would be unlikely to ever tell me...

DeeJay said...


A1. 155-160(5)-160(5)-160(4)
A2. hand placement- bum, stomach, chest, temples
B. after faling the round of 9 twice at 4 reps I decided to do 55 for time. I was toast so it took me a long 17:45 all kipping to an abmat off 25kg plates.
C. 25x3

my body is smoked!!

C. 135x4/145
D. 15/10+5/10+5/8+7

Still learning snatch form and technique.

Part 2.

Everything unbroken but took too much rest to ensure so. Kind of embarrassed now that I see the other times...Oh well, back at it tomorrow!

Eric Montgomery said...

Part 1
A. 95x3, 100x3, 105x3, 110x3, 110x2 (dropped under rep 3 a little)
B. 110x3, 120x3, 125x3, 130x2, 135x2
C. 125x2, 130x2, 135x2 (ugly), 125x2, 125x2
D. 12, 15, 15, 15. Wasn't comfortable on GHD for first set so readjusted and made a big difference.

Part 2
18:41 total time including rest. Rounds were 2:01, 1:57, 2:16, 2:17, 2:14. DUs not unbroken.

Notes: Had to use 18" box. DUs were atrocious--realized in warmups that I wasn't going to be able to do them unbroken and during the workout I couldn't string any more than about 8 in a row. Been messing around with a few different ropes lately but it shouldn't have had that much of an effect on my timing.

OPT said...

julian, rest and come back when it is 100%

curt m, skip it and join in after

ROBO said...

Joey Get betters soon bro you gotta kick some ass in Cali.

Part 2
1- 1:21
2- 1:27
3- 1:40
4- 1:42
5- 1:55

Something is seriously wrong with my power snatch from the ground. I'm having not trouble with the high hang and can do more with than from the ground. I don't think I'm being patient enough and letting the bar come to me. I also feel like I'm picking up the ground too quickly, not waiting on the speed throught the middle. I'm a little frustrated but I know it will come.

k.jones said...


A. 115/125/130/135/140 3reps for all

Aggresive run/row,jump warmup to fire up the engine.
A2; UB. The pain on the quads was a mind screw
B: Hit 10 then 9 which is a record for this crocodile. My next attempt was 7 and a 1 then the wall of China came down on my back and singles were all that was left. Had to call it a day with class looming.
Absolutely smoked from the cycle...and lovin the work!

B: 90
C: 95 failed 100 technique went to hell

tried to focus on technique weird that my muscle snatch felt the best??


no time to do part two. Plus working back on slowly

Part 2


Snatch needs work. Did not have my mind in it on part 2. Not happy

Stephen B. said...


part 1:

A.95/105/110/115/120...I'd never done these before...didn't know what to expect...tough
B. 135/140/145/155(2)/145
C.135/145/155(2)/155(1)/155(3)...I rushed the first two sets of 155 which resulted in a good deal of slop...for the third set I took my time and focused on staying tight off the floor with an aggressive third a result, the last set felt much stronger
D.UBx4...getting stronger, still hurt like hell

rest 15 min

Part 2: fckkkkk!!!

screwed this wod up 10 burpees instead of 15...totally frustrating because I felt real focused and strong on the wod and had no breaks except 2 rd of DUs, which I had to re-do when I missed on 6th rep...burpees, bj and DUs flowed real well and felt great...
felt totally recovered for each round

so, my times (none of which count) with 10 burpees...all UB rounds
1:06/1:10(1 re-do on DUs)/1:04/:58/:58

Finally back into this program after getting my big toe broken about 12 weeks ago. I have been dabbling all around crossfit because of limitations the past couple of months. Some of the first double unders and box jumps I have done in about 3 months.

8 min rest

Part II: 1:24/1:36/1:54/1:52

Helped coach boys baseball practice after work tonight and got to gym at 8:00. Would have been easy to skip this one but I wanted to hit the burpee metcon. It's 10pm now and I'm beat but it's almost friday dawgs! Ouuuuu

Geoff, we're missing you around here!

Worked on form tonight with the snatches so I kept the weight at a managable weight. My neck still isn't ight may need some more time off(took Tuesday and Wed off)

part 2 tommorow as ran out of time today,and it may be easier on the neck,then the overhead work

Ben Priestley said...

A. 55#, 65, 75, 80, 85
B. 85#, 85, 85, 85, 95
C. 95#, 105, 110, 115-1, 115-1
*D. UBx4

1:34, 1:32, 1:31. Stopped here

Notes: Musc.Snatches went well, but remaining work was not flowing. Unclear on if there is hip action initiating High Hang Power Snatch or if it's just a tall shrug and drop. Decided it felt better if I was slightly over bar and then could open hips. That's when I jumped to 95#. Between part1.C & D, I rested 1 hour, and then I did my home affiliate's wod. It was For Time: 50 box jumps (24"), 50 Push Press 65#, run 800m. I finished in 6:36, went all out. Because of the extra work, I only did three rounds in part2.

2011 part 1:
A: 85#, 95, 100, 100, 100
B: 110# - to heavy, 100, 100, 100,100
C: 105, 110, 110x2, 110x2, 110x2
D: all unbroken, hammies felt it

notes: A, B, C - good workout from a technique point of view. Unfortunately, there was a fair amount of pressing during B and C. Third pull not aggressive enough.

2011 - performed 6/24/10 (still one week behind for scheduling reasons)

A. 75, 85, 95, 95, 95 (got ugly, need to make smaller jumps and focus on speed)
B. 95, 105, 115, 125, 130(2) - last set was ugly

C. 115(2),115,125(cadence off),125(cadence off), 125


rested ~ 10 minutes.

1:17, 1:17, 1:16, 1:18, 1:17 - this felt great! Finally a piece of these workouts that didn't cripple me.

My snatch needs lots of work. Feels like my weights are way lighter than they should be.

2011-performed on 6/24/10
Part 1:
A: (all x 3)--95,115,125,135,145 (little bit of press on last rep)
B. (all x3)--135,145,155 (landing too wide), 165 (landing wide and last one had a little press), 165 (ditto)
C. 155(3), 165(3), 175(2+1 with some press), 180-F-inj--tweaked something in my wrist and that was it for snatch. Pretty bummed, as I was hoping to get close to a PR. Felt good pop, but still need to work to keep from going too wide.

D. All as rx'd.

Part 2:
2:10 (bricked on DU #25 at around 1:30)

After first set, took longer rest before DUs. Still finding comfort level with UB stuff. This was a great burner.
