, overhangs and especially roofs place special demands both in terms of technique and equipment as well as the constitution of the climber. With increasing steepness the loading on arm and hand muscles increases, because the feet can support less and less of the body weight. Rest points where the muscles can be relaxed, especially no-hands rests, are rarely found in overhangs. Climbing techniques to tackle overhangs include placing the body's centre of mass as close as possible to the rock and striving for the highest possible body tension. Many climbing techniques such as the foothook are almost exclusively used in overhangs and roofs. For a long time in

Severe climbing routes that feature overhangs and roofs include Separate Reality in the USA and La Rambla in Spain.
