wheels! not twigs
I have always tried to have a bigger, stronger partner than you when training wheels, reason being you will have to bring it or look like a girl training legs..
5-10 min recumbent bike to get blood flowing(pp)
light but high reps on leg extensions 4X20
now you're ready to start the actual workout:
leg press start with 600-800lbs on first set, jump 90-180lb each set even if you have to brace your knees with your arms crossed.....
right to hack squat, find your weight.. start 2 Cadillac's on each side and drop into the bucket, blast them out with more control on the down force( will save you knees) all 4X20
and last squats.. as heavy as you can for 4 set min 15-20 reps(burn out) I promise when you pull into your driveway, you just might fall as you try to stand up as you exit your vehicle....
most important thing to keep in mind is your focus, goals, and safety...
if you blow your knees out, where would it leave you?
I'm all for lunges, but they do real damage with heavy weight, so if you like them maybe use as a change up for burn out. light 25-45lb dumbbells walking lunges. with wheels you have to break thru your comfort zone and that's why I mention a partner to push and hold you accountable....
