(depends on 3) The foldable weight training sled of claim 3, wherein the training information includes a duration time value, a distance traveled value, and a speed value. ### Claim 5 (depends on 3) The foldable weight training sled of claim 3, further including a second measurement device located on the top side of the chassis, coupled to the second axle to measure rotation of the second axle and display training information corresponding to movement of the foldable weight training sled along the support surface; wherein the first measurement device comprises a display facing towards the first end, and the second measurement device comprises a display facing towards the second end. ### Claim 6 (depends on 2) The foldable weight training sled of claim 2, further comprising a braking device for applying resistance to rotation of the first axle; wherein the braking device comprises: a third axle physically coupled to the first axle, and a variable resistance mechanism coupled to the third axle. ### Claim 7 (depends on 6) The foldable weight training sled of claim 6, wherein the third axle is coupled to the first axle via a chain drive. ### Claim 8 (depends on 1) The foldable weight training sled of claim 1, further comprising a first measurement device located on the top side of the chassis displaying training information corresponding to movement of the foldable weight training sled along the support surface. ### Claim 9 (depends on 8) The foldable weight training sled of claim 8, wherein the first measurement device comprises a timer. ### Claim 10 (depends on 8)
