Once Blake returned to the training room with Bret, they separated once more before jumping off and heading in different directions. It could not be self training if you have others around you. Luckily the areas were large enough for multiple different jump off points.
Above the training room was a bridge that you could traverse to reach the different jump off points for the different zones. Blake wanted to deal with the forest training since it was mainly what he would be expecting at this time.
After all, he was now in a forestry area. In truth, even in his past life he never made it to any deserts or frozen tundras. But this time, he was keeping a much better eye on his surroundings. He did not wish to end up being surrounded by bees again. Such an experience is enough to traumatize some people, but Blake dealt with it without issue since he has seen much worse.
