Isometric holds raise blood pressure: breathe through every hold, and check with a doctor first if you have high blood pressure, a heart condition or a joint injury. Make sure any door frame, bar or step you use is solid. Stop if you feel sharp joint pain. If you're under 18, keep the effort medium and skip extra weight. Winter Arc challenge: free to enter.
