So its starting to get sunny outside and im getting bored of doing weights and want to concentrate more on my biking/swimming/running for the upcomming triathlon season. Ive cut down to working out 2 days a week now and im wondering if i can maintain muscle strength/definition(yes, im vain ) for the rest of the summer just cutting down to 1 day a week. I just want to maintain my size and strength. Is this possible?
Strength and size will decrease, cardio burns muscle rather well. However with the burning of fat as well your definition will likely increase.
To give you an example. In bodybuilding they go through a bulking period where muscle and some fat is both gained. Then a bodybuilder will enter a cut where decreasing fat is the main goal. Now a small amount of muscle will also be lost, but in a cut the man will look larger because he becomes more defined, even though he has less muscle mass.
I gain on two 20 minute, full-body sessions a week, and hold about even on one. Don't know when your first tri will be. I'd say do two short sessions until 3 months before, one session until two months before, then nada.
Every one is a little different, but it's easy to find out what works for you. Cut back to one per week for a couple months. Keep a record of the weight you lift with each muscle group. If the weight you're able to lift goes down, you're getting weaker. If the weight lifted stays the same, you're maintaining your strength.
As for looks, let the mirror and the glances you get from others be the judge.
