When I was on Atkins and doing BFL strengh training, I literally HAD to up carbs before a workout. I got the worst muslce cramps I had EVER had in my life - and I had already been doing the strength training for a very long time, so it wasn't just that i was starting a new program.

I didn't up carbs in general, I only did it 1/2 hour to 1 hour right before workout. Also, taking cal/mag supplement is a MUST. Potassium works quickly and is a also a must if you're having any muscle probs.

Good luck!
