An agility ladder kit suitable for forming an agility ladder, said agility ladder kit comprising:

• (a) one or more agility ladder ground strips, wherein each of the one or more agility ladder ground strips comprises an upper strip major surface, a lower strip major surface opposite the upper strip major surface, a first strip end, a second strip end opposite the first strip end, the first strip end and the second strip end being separated by a strip length Ls, and opposite strip side edges separated by a strip width Ws;
• and
• (b) one or more agility ladder strip connectors, each of said agility ladder strip connectors comprises:
• (i) an upper connector major surface, (ii) a lower connector major surface opposite the upper connector major surface, (iii) a first connector end, a second connector end opposite the first connector end, the first connector end and the second connector end being separated by a connector length Lc, (iv) a first connector side edge extending between the first connector end and the second connector end, (v) a second connector side edge opposite the first connector side edge, and being separated from the first connector side edge by a connector width Wc, (vi) at least one strip receiving opening within each of the first connector end and the second connector end with each of the at least one strip receiving opening (a) sized to receive the first strip end or the second strip end of one agility ladder ground strip of the one or more agility ladder ground strips, and (b) having a strip receiving opening width greater than the strip width Ws, and wherein (1) at least one strip receiving opening at the first connector end connects with a corresponding strip receiving opening at the second connector end to form a length-extending connector channel extending from the first connector end to the second connector end, and (2) each length-extending connector channel comprises opposing channel side edge portions that extend along a complete length of the length-extending connector channel between the first connector end and the second connector end except along an intersection of the length-extending connector channel with a connector channel extending from the first connector side edge to the second connector side edge, and (vii) at least one connector channel extending from the first connector side edge to the second connector side edge with each of the at least one connector channel sized so that one agility ladder ground strip of the one or more agility ladder ground strips is capable of extending through the at least one connector channel.
