Use the runway near the Power Bomb room door to jump towards the Gauntlet Entrance room Bomb blocks and break them using the temporary blue effect from SpeedBooster. Using the full runway, a one tap shortcharge where the tap is at the top of the lowest slope, jump and then Morph once Samus begins descending to bounce through all of the Bomb blocks. A controlled release of the jump button works in place of the shortcharge, where the bottom of the thick dark line in the background at the top of the room works as a visual cue.
