Since my knee injury my fitness has dropped off....
Have you thought about Cross Trainer/ elliptical trainer? Very low impact. Helps me a lot, used this a lot after I did my knee ligaments bowling at 13!
I'm not the biggest fan of the treadmill!
For me, fitness is a big part of my life.
Unfortunately, I'm not gifted with 'fit' genes, meaning I have to watch what I eat and continually exercise!
Though it's good in a way, pushing yourself and reaping the rewards for it later.
This is my normal week at the moment:
Monday: Weights- Chest and Triceps. Followed by 20 mins on X-Trainer at 65% of my heart rate (HR is 220 minus your age)
Tuesday: 6.30am Bootcamp style outdoor work out for 1 hour, Interval training with lots of focus on the core. Tues night: weights- Legs and Lower back
Weds: normally day off in winter, Evening league cricket in summer months.
Thursday: Boot camp again- different trainer to Tuesdays, same values as before. 6.30pm Football training, 8.30 Weights- Biceps and Ab's.
Friday: Weights- Shoulders Back and Traps, second favourite day behind chest and Triceps!
Saturday 8.00am Bootcamp again. 3.00pm Football
Sunday: 10.30am Football
