Here are two breathing drills to help you see the power breath gives you.
Start by standing and slowly squat down with your back aligned going down in small steps as you exhale and relax. Once you are down move your hips and shoulders a bit to relax in this hight as well and slowly climb up in small steps using the inhale to move the body. This may seem strange at first but will help connect the gaps in letting the breath move you.
The second drill is just like the first only you drop and raise one hip at a time while keeping the spine aligned from it upwards.
Try them a few times with awareness to the small happenings and check how you work afterwards.
