All you need for this total body strength workout is an interval timer. If you don’t have one on your phone, I recommend the Interval Timer. Set your High intervals for 20 seconds, your Low intervals for 10 seconds, your sets to 8, and repeat 5 times. I recommend 30-60 seconds cool down between rounds.
