When I do Kettlebell swings my lower back gets pumped full of blood to the point that it is completely blocked and I cannot move. I just have to stop, drop the weight on the floor. Those who train with me do not have this problem, even though they are weaker than me and using more weight.
I have had my form checked a few times (by certified kettlebell instructors) and been told every single time that it is great. I have checked instructional videos and then practiced the movement using mirrors to self check my form again. We can pretty much rule out technique.
I do not get any problem when deadlifting, but I can get lower back pumps if go for a jog (which is rare).
My supplements are protein powder, fish oil, multivitamin and creatine. I do use Craze as a preworkout occasionally, but not less that 36 hours before intending to use kettlebells. I know AAS can cause pumps, but I don’t use them.
This situation is seriously annoying. Anybody had this problem and found a solution?
My current plan is:
- I just got a foam roller yesterday and have started to use that on the problem area daily.
- High frequency. Use an embarrassingly light weight KB for a timed set 3 times week. Increasing time rather than weight.
- Stretching - touching toes and cat stretches etc.
I hope someone can help.
