Will substituting yoga for weight training still keep me toned? Suresh Shenoy, Nagpur Different activities have different physical, physiological and mental benefits. Depending on all of the above goals, one engages in activities that are aligned with those sensibilities and provide the benefits desired. Depending on what kind of yoga you are doing, the benefits are largely joint stability, mobility, muscle flexibility and some strength benefits as well, if doing inversions and arm balance poses etc. However, if your goal is to increase muscle strength and size, then yoga is not a substitute for that goal even though it is a great complement to that goal. So do yoga by all means; it’s a wonderful adjunct to all fitness activities and complements almost every fitness goal. But having said that, if you want to increase your muscle strength, include weight training into your routine two-three times a week at least. Being slim and ‘toned’ is a cumulative effect of exercise and right nutrition. A combination of different exercise routines (aerobic, strength, mobility training etc) will give you a more rounded and broader fitness benefits and keep you in better shape mentally, physically and physiologically as well.
