What's easier 10 reps of a back squat or 2 reps? It all depends on how heavy you lift. They should both be challenging because with 10 reps you will lift lighter but have more time under tension, however with 2 reps both reps should be tough as the bar should be heavier. For the squats in class work on building up as the reps decrease.
