5B// SLOW NEGATIVE CHIN-UP
SETS 3 REPS 1 REST 90SEC TEMPO N/A
Stand under a pull-up bar and jump up to grab it with an underhand grip, hands shoulder-width apart, so that your chin is above the bar. Squeeze your core, biceps and upper back muscles hard and lower yourself as slowly as you can – aim to take 30 seconds. When your arms are straight at the bottom, drop to the floor.
