Pre-workout supplements with crossfit?

Recommended Posts

Having just played around with a crossfit workout recently, and found my heartrate went through the roof, it got me wondering about pre-workout supplements. Are they used much in the crossfit world? Is it even a good idea to combine heartrate-spiking exercise with heartrate-spiking stimulants?

Or are you crossfit peeps so hardcore you don't need pre-workout supplements?!

Got mates that take pwo for crossfit and its mainly due to them being tired from work but wanting to go as hard as they can after a long day.

Could imagine things could get pretty intense though

Coffee for me as part of my breakfast and its very strong. Ive tried PWO before and I ended up having heart palpitations and getting very very light headed. So for me personally it jsut the quad shot of coffee in the mornin and then its hit the gym time.

Ha, I used to do 4-5 quay shots a day and still sleep at night best sleeps come to think of it. Now just the one in the morning, but have to eat breakfast to line the stomach.

4 serves of coffee around 150~200mg caffiene total. about the same as in a single serve of most off the shelf PWOs but without all the extra garbage which may or may not be on the label so a pretty decent alternative unless caffiene alone doesn't stimulate you... or coffee makes you feel like going to the toilet lol. personally i just use a 200mg caffiene capsule and a serve of raro or banana for my fake crossfit style sessions doesn't seem to bother my heart these days but rewind back few months ago when i wasn't used to the cardio style stuff i'd feel the heart thumping like crazy

Recently tried some PWO supp with 300mg caffeine and added a 200mg capsule and nothing.  Double scoop C4 Extreme + 200mg caffeine capsule was also a miss.

 

Possible my heart actually stopped weeks ago?

thats ridiculous man when you say nothing do you mean it didn't even affect your sleep? crazy high tolerance right there i would stop with PWOs/soft drinks/stims for a couple months and detox if i was you lol.

Detox would be the sensible thing to do; kinda reset the CNS and sensitivity to stims.  I'll give that some thought.

 

The day of the double C4+caff I would have gone to bed maybe three hours after training and slept fine.

 

I certainly wouldn't recommend a stack like that before a crossfit session!  I have to assume blood pressure is still being affected and that could get funky.

 

In before idiotic TV3 expose....

I've found a huge difference between PWOs, some great some absolute rubbish.  I use Assault or Beta Cret all the time and find them good.  I train early am so need something as a kick start but I find coffee to dehydrating for Crossfit but fine for lifiting.

Old thread, but taking a PWO and doing Crossfit nearly killed me. Heart rate was way too high. Felt awesome to get the kick and motivation on tired days, but definitely something I would personally avoid. Gym lifting has rest periods. CF does not (unless you consider the running a rest).
