Question about /w/ and /r/ blocks

Question about /w/ and /r/ blocks Hey everyone, I'm not sure if this is the correct place to post this, but I figured people here might have a lot of experience with this. Whenever I try to make a W or an R sound, my lips tense up and I completely block on the sound. I understand how to get past almost every single other block, but for some reason, I can't get past these. Could anyone help me develop a strategy to tackle these sounds, or provide material I can read to help me learn about it myself? Thanks in advance, I appreciate it
