Should i rest my muscles? I've been working out my arms daily and i feel like my arms and back are "fatigued" if that makes sense, i saw a video that said that muscles need 2 days + good protien intake to rest so if that's the case Should i workout less intensely daily or do i have to change my regiment into working out every 3 days or working a seprate muscle every day(bicep tricep forarm+shoulders)?
