This workout means Every Minute on the Minute - which means at the start of every minute you do a certain number of reps of an exercise, rest for whatever remains of that minute, then start the next exercise when your next minute starts.
Minute 1: Squat, lift, squat - 15 reps
Minute 2: Push up to shoulder press - 10 reps
Minute 3: Forward lunge with alternating arm row - 20 reps
Minute 4: side hop with circle arms - 25 reps
Minute 5: burpee variation with reverse lunges - 8 reps walkouts, 10 reps 'jump' version
Here is a video where I demonstrate each exercise - watch this for coaching points and variations / modifications:
Here is a follow along video when you workout with me. You can see my struggles with counting my reps whilst talking (what's new?) but that's okay as you count your own reps and work at your own pace, just start each minute with me and go with the timer! I get the first number of burpees wrong and talk about 10 or 15 when I should have said 8 or 10, but you can always do 15 if you prefer :)
