Hi Siobhan,
Yes, I have fairly solid legs. They are one reason at my weight that I can fit into a size 8 pants and sometimes a 6.
Today I had 3 and we did my Weights , Cardio and more Weights 1 which is intense and 55 minutes long.
Then I did 45 minutes of weight work including barbell and dumbbells plus floorwork for abs ,legs and glutes.
Nice workout for you.
Mind you I don't go terribly fast on the elliptical, I do between level 8 and 10 on the fat burn setting so it is mostly endurance, will put the elevation up 1 or 2 notches also.
Have a great day!!
