2. Position your centre of gravityWith the speedbag fitted hang the LIGHTNESS up, sit in it and closethe chest strap. For the ideal centre of gravity position in the harness,and as a reference point for all further adjustments you should– first without using the support of the speedbag – slide into the seatso that your weight is supported over the main support strap (3); sothat you can balance there (centre of gravity zero position). The mainstrap is not adjustable and serves as the main support.Info: To get your centre of gravity in the right place in theharness, sit on the main support as if swinging on a trapeze.3. Setting the speedbag lengthNow you can adjust the speedbag length by means of its footboard.Do this by moving the positions of all four overhand knots symmetrically.With the correct speed bag length, both legs will be supportedon the footboard with light pressure, without effort. All four speedbaglines (4) should be under equal tension and symmetrically set.You can test this by checking the ends of the speedbag lines. If thespeedbag length is not correct there will be noticeable creases in thespeedbag.14
