@Zalco/bring back Sophie!, here's what I've done daily for the last several years - Laying on my back on the floor, knees bent.
Lift one leg, return to floor, then the next, and "March" 250 steps
Still on back, Knees bent and together, lay them over to touch the floor, hold for a brief count and then do the same on the other side - 50 reps, 25 for each side
Arms behind head and Knees bent do a modified crunch sit up. 10 reps
Same position but this time touch left knee with right elbow, then right knee with left. 10 for each leg
Laying on back, place a belt or strap over your instep, holding the other end, and raise leg perpendicular in the air. Apply modest tension and hold for 45 seconds. Repeat with other leg. Do each leg 3 times
Standing with my hands on a dresser, kick each leg backwards at a 45 degree angle, return foot to floor, repeat. 10 times each leg, then switch, then repeat cycle again, 3xs total.
At one time I was doing a 10 minute "wall sit".
My PT started me on these several years back and I continued, adding reps over time.
I really look forward to starting my day doing these now. Never miss a day.
Three mile walk daily, weather permitting but I've always walked..
