There are a lot of things to get used to with this bike. Tightening your upper body muscles ,shoulders, arms and hands is the wrong thing to do. Core muscles should hold you up, not your hands. Bend your elbows, relax the upper body and ride it. Power flows from your stomach and legs, not your arms and hands. It takes time to build the core muscles and endurance as you are not used to using them.
Edit: To clarify, I am constantly reminding myself not to lock my shoulders and quit resting on my hands. More so for me on long rides. When my hands get sore or numb, its not my fit, I locked my elbows and am resting on the bars. Shoulder pain, locked my shoulders. Fatigue sets in and I have to remind myself that I just need to relax and use proper form. Happens less and less now.
