Barbell squats (I use a smith machine so I can do 120 pounds or so) 20 reps
Bulgarian dumbbell squats (or lunges with one leg up 15 reps each
Dumbbell step up with leg kickback 15 reps each
Repeat 3 times. No break until one round is done- then just enough to feel like you can jump in
Dumbbell straight leg deadlift 20
Dumbbell hamstring curl 20
Reverse back extensions (lifting legs instead of torso) 20
Repeat 3 times no break until one cycle is complete and it's short!
Sometimes I add in some machine and specific leg moves here. Addiction, or rear kick etc... Same cadence: 3 exercises- 20 reps, 3 times through.
Plyometric lunge jumps 20 each
Static speed skater 20 each
Plyometric speed skater 20 each
Stability ball hand off crunches 15-20 OR jacknife stability ball planks 15-20 each
Repeat 3 times. Same break schedule.
What's great is really you don't need much equipment for the routine!
Hope it's useful.
