Yup grids and one or two jumps is very common/popular. A good instructor will tailor their setup for the group they are teaching at the time, and not JUST in height either. The more experienced groups get trickier lines and jumps with difficult striding while the really new kids do one jump at a time. Starting with poles if they have to!
My regular jumping coach is ALL about the rhythm and takeoff spot. If you can't get those right over small jumps then you can't go higher. You can only increase your height if you get it right every time. It's frustrating for me because Monty and I are well above the level that my coach has us jumping, but Monty likes to take the long spot and because of that, we have to work on getting the right spot.
Yeah. My coach is an all-round coach but anyone would think he coached hunters, the way he preaches about position, striding and takeoff spots! Ah, but he gets the results, so I can't complain.
Something else you will need to remember is that the best coaches are REALLY hard on you! I'll finish a lesson and Monty and I are both dripping with sweat, even if it's freezing.
