>>73264673>if you're in your 30s and up, and do it above 2 times you will have back spasms.The fuck? I'm 32 and have never had that issue and 2 is my normal.
Just do some deadlifts and situps anon. You shouldn't be having back muscle issues in your early to mid 30s, realistically if you have a proper routine you shouldn't get those until well into your 40s.
