The Theragun Mini Plus pairs percussive massage with a heated attachment that reaches 131degF in under a minute, built into a body small enough for a gym bag or carry-on. Three massage speeds and three heat levels work together or on their own, and a quiet, adaptive motor holds its power when real pressure gets applied instead of stalling out. What Our Gearhead(R) Experts Are Saying:"I was skeptical heat would do much beyond feeling nice, but working it into a tight calf after a long run loosened things up faster than percussion alone ever did for me. The motor never once bogged down, even when I leaned into a knot with real pressure."
