I'm currently overweight and have been doing the 5x5 program pretty consistently but want to integrate more cardio into my workout plan. After jogging, my legs/knees feel pretty tired as it is and am afraid of hurting my knee (already have a torn ACL). Does jogging/running suffice as a leg workout?
Please use low-impact exercises till you are fit enough to run. A lot of people make the mistake of using running as an exercise to get fit which can backfire.
- Rowing - Uses upper body as well and low on impact.
- Ellipticals - Again relatively low impact
- Spinning - Relatively Low impact
You are doing good in following 5x5, please continue that and build on strength and with calorie deficit you will lower body fat. Patience is the key!
