Leg weights

PowerCranks. No I haven’t got them.

Goose, Would you happen to know if/why cycling (considerable distances) would be deprimental or have negative side effects with regards to tendon strength, elasticity & sprint times?.

What I mean is…

I can put the bike away in the garage for 3 months & train specifically with just weights, plyo’s & sprint training & get considerably fast. 3 months passes, the bike comes out of the garage & I’m now on the bike, still doing weights, plyo’s & sprint training & I’m suddenly slower.

The explosion isn’t there as much? What does the bike do to my body?. Why is it my power, strength, elasticity etc just “dissolve” from having just jumped on the bike still doing the same training prior & putting up the same numbers in the gym, same volume of plyo’s?.
