If I’m planning on riding for more than an hour, I always do warm up exercises & if I remember “warm down” exercises.
Ride magazine printed some a few years back & it definitely makes a big difference as I can ride “spiritedly” all day without much in the way of aches & pains.
The areas I concentrate on are:
LOWER BACK, hold right elbow with left hand & gently twist upper torso 10 times, swap to other elbow/hand & repeat.
HIPS, stand on left leg (maybe hold onto something until you get used to it!) lift right leg until thigh is parallel to ground, move right knee to the right gently until you feel the hamstrings pulls a little bit, return knee to in front of you, repeat 6 times.
HIPS, BACK COMBO, stand with feet shoulder width apart, arms out in front of you as if holding handlebars, squat down as if on your bike & back up again, repeat 10 times.
SHOULDERS. shrug shoulders up, down in a circular movement, 6 times.
NECK, gently turn your head left then right as far as is comfortable 6 times.
WRISTS, roll wrists in a circular motion 10 times.
Sorry it’s a bit long, but really only takes 5 minutes & you may look/feel a bit silly, but you won’t be the one aching at the end of you ride
Enjoy your 790, I’m smiling every time I ride.
