People on here can be super nonchalant about exercise and going to the gym but they don't think about what lies ahead of them if they don't put the effort in now.
I can attest to that. At 70 I still ski, ice skate, play tennis, swim, hike and do a hundred things in my very active retirement. Whereas most of my friends are inactive, with impaired mobility and all kinds of aches and pains.
I know I’m harping on about this, but the investment you make now will pay off as you get old.
It doesn’t have to be regular gym sessions and 5k running several times a week. Grab a few minutes here and there:
3 minutes jumping jacks or squats, or a 2-minute plank while you are waiting for the tea to brew.
a short yoga session while watching TV (Kassandra, Adrienne, Livinleggings etc - find one that you can relate to)
a Growingannanas 12 minute Tabata HIIT mini-workout before you hit the shower
7-15 minutes with the lovely Lucy Wyndham Red (her short glutes & thighs workout is great)
add weights to increase effectiveness - dumbbells on your shoulders when doing squats, or goblets squats with a heavier weight; when you are ready to challenge yourself, check out Caroline Girvan…
Above all, walk, walk, walk - walk as much as you can, preferably with a weight (ankle, vest), and take the stairs wherever possible, instead of the lift.
ETA…. It’s TABATA……… bloody autocorrect!
