Tik Tok Treadmill Workout
If you're on TikTok, you probably would've seen this viral fitness hack going around a few months back. Dubbed the '12-3-30′ workout, the hack simply involves walking on a treadmill. More specifically, walking on a treadmill at an incline of 12, a speed of 3mph (that's 4.8 km for us Aussies), for 30 minutes straight.
